- 1.) In the horizontal warps, the players enter/exit super fast, would be more polished if they enter/exit at the half of the current speed.

- - Mouser shoots too few bombs, it should throw bombs like crazy! like 1 bomb per second or at least one bomb every two seconds!
-When you hurt Mouser it produces the sound effect "shell kick" instead "Birdo Hit" as it should.
-When you hurt Wart it produces the sound effect "shell kick" instead "Birdo Hit" as it should.
-When you hurt the SM Thing (NPC-205, this) it will produce the sound effect "shell kick" instead "SM hurt" as it should.
-The animations of Mouser, Wart and Birdo could be more polished too (then they get damage) those animations could plays the double of faster.
-The shell of the bosses which follows you could get speed a little faster (but with a speed limit of course).
-If you throw a bomb to Wart in the upper edges, it won't recognize the explosion and won't get damage.- Spoiler

-Wart can get damage with fireballs but without play the same animations when it got hurt.
-With the new fixed to the hitbox, you can smash enemies that aren't supposed to be smashed. I've seen this error with many NPCs, I'd suggest appy the same configuration of the NPC this new "hitbox" too. :)- Spoiler

-When the Giant hammer falls hard, if the player its on floor it could also make a diminute jump-movements like it do in SMB3:- Spoiler

-Would be more polished if the Blaarg eyes don't shows for too many time, only a few like in SMW/SMBX 1.3:- Spoiler
- SMBX 1.4:

SMBX 1.3:
There are two little problems with SMB2 bushes:
- When the player is above to a buried it will elevate 1 pixel more, this shoudn't happen.
- The burieds should be two pixels more up than they already are (basically the should have 0 as a value in GfxOfSet (it's easy to fix trough the editor anyway)
- The frames of the burieds are unsyncronized, would be better if they are syncronized by default. :P
- When a player got a coin from a Buried, when this player stops to press "Run" key (I mean when the player "throws" it), this coind will be collected instead float as it did in SMBX 1.3, that's a good feature, however I'd suggest add the sound effect "coin" instead "shel kick" when this happens.
By last, SniftGuys has wrong animations. In SMBX 1.3 when they are moving and the Snifguy with shoot that thingy, the frames stop, in SMBX 1.4 it doesn't:- Spoiler

In SMBX 1.4:

2.) The generated objects (up direction) in "warp" (such a power-ups/NPCs from a generator) appears a bit too fast, it would be more polished if they appear a bit slower (like the half of speed slower?).
3.) When you hit a block with an item, this block make a little movement to up and down, in my opinion this movement could be the double of faster that it already is to be more polished. With this also will be more comfortable hit blocks with many coins and would remove some minor bugs.
SMBX 1.3:
SMBX 1.4:
4.) The block-526 makes the sound effect of the SMB3 block when its breaking, this is wrong, this block already has its own sound effect (SM Block Hit).
5.) When Yoshi is descending it still makes the flight sound, this shouldn't happen, Yoshi should descend without make noises.
Also Yoshi can split enemies recently ate (I'm pointing this again because I noticed I didn't specified how it did in my last post):
When Yoshi eats an enemy, if you press quickly "run" key it will split it out. I guess a good way to fix this would be disable the movement to Yoshi that sticks out his toggle for at least 5 frames once he ate an enemy (I don't know if this is too complex to do, anyway it's a very menor thing).
6.) Toad can make double jump in water. Peach also can make her "flight" (this will produce a weird swimming).
7.) When a player its under water, touch the floor, and get-out of the water, it will make the sound effect "jump", which is wrong, once the players touch the water this sound shouldn't be played.
I also woud like to mention than fireballs has wrong physics when they are in a section with the setting "Underdater" on (interestingly this only happens in underwater sections, if the water was placed by liquids it will work correctly).
8.) When the player is under water above a platform, it shouldn't be able to slide, instead slide the X speed would be restarted to 0 (like happens in SMBX 1.3)
Here's an example in SMBX 1.3:
In SMBX 1.4:
9.) You can't duck with Peach and Toad when they are swimming, in SMBX 1.3 they were able to do, in my opinion would be nice if they can duck again.
10.) Peach can make spin jump when its climbing and the player press "alt-run" key.
11.) When Mario, Luigi or Toad are climbing a vine and make a spin jump, it won't produce a sound effect.
12.) There's an annoying sound glitch:
Also I'd like to suggest produce a little push to down when a player its under water and has hit a block, like in SMB3.
13.) This is really minor, but very important thing. When the players are in the shoes, they can make a little "double jump" for a little momment. Once the player touched the floor it can make this double jump on the first 15 frames (0.2 secs) approximely? I don't know what's the exactly value. Anyway I made am accurely test and the number of frames the players can make this "double jump" should be adjusted to 22 frames (0.3 seconds). This is very important because when you use a shoe with Peach, it's basically break. :/
14.) Peach makes an involuntary flight. To replicate this bug just jump and keep pressing the "jump" key while you move laterally (this won't work if you don't move). As I know the flight with Peach when you keep pressing a key (jump or alt-jump) was disabled on SMBX 1.4.3:
15.) Here are some minor things to improve in NPCs that requires intervention of 5438A38A, some really small suggestions.
16. When Toad hits a block with multiple coins, they should be triggered much faster like in SMBX 1.3. Also when multiple coins are generated, each coin should produce the sound effect "coin", in SMBX 1.4 there are some missing sound effects, it just produce this sound effect at once. Every time a new coin is generated, the block shoud self-make the effect like if they was hit by the player (I mean make a velocity up&down). Also Peach when hit multiple blocks hit coins on one jump (using his hover), the game won't make the sound effect "block hit" various times, only one time.
17.) The effect-10, effect-73, effect-75 and effect-132 could have a faster frame speed to make the game feel more natural (the frame speed of these effects can't be edited). Also the effect-1 could have a higher gravity (fall a bit faster) to make a more natural effects when breaking in block like in SMBX 1.3 or other Mario games. All the effects overall could have just a little more of gravity, would be better if them fall just a bit faster (in SMBX 1.3 and in other Mario games overall the gravity of the effects is a bit faster than in SMBX 1.4).
