- The player shouldn't bounce when jump (normally) in a SMW Goomba, but it still dies to other jumps (spinjump/yoshis/shoes).

1.3:- Spoiler

- Similar to the previous point, the player shouldn't bounce in a bomb-omb, no matter what kind of jump it is:
1.4.5:- Spoiler

1.3:- Spoiler

- Fireballs and ice balls have wrong interaction with trampolines. Fireballs only interacts with them after their first bounce, while ice balls seems to not interact with them at all:
- Spoiler


- When you kill a frozen enemy by hitting it from below, it doesn't give any score:
- Spoiler

(Also would it be possible make the particles sparse a little less please?) - Skulls don't freeze when the player gets a hurt/grows up like other platforms do:
- Spoiler

- When the player hits a block with a coin above, it should show the coin effect (like if the block had a coin inside):
1.4.5:- Spoiler

1.3:- Spoiler

- Talking about blocks, the block-169 should produce the sound effect "Switch" when hit.
- The following NPCs shouldn't be able to be hit by a leaf (set NoLeaf to all of them):
- NPC-92 (Onion, it's the only Veggie that has this problem, don't worry about others)
- NPC-134 (Mouser's Bomb)
- NPC-241 (POW Block)
- NPC-240 (Clock)
- NPC-248 (Item Box Clock)
- NPC-249 (SMB2 Mushroom)
- NPC-192 (SMW Checkpoint)
- NPC-35 (Green Shoe)
- NPC-191 (Kuribo's Shoe)
- NPC-193 (Lakitu's Shoe)
These NPCs have wrong interactions with leaf:- NPC-135 (Bob-Omb SMB2)

- NPC-153 (SMB1 Bad Mushroom)

1.3:- Spoiler

- When the Grinder (npc-179) is in a SMW line and is set to "Don't Move", it still moves (however, it stays still in SMBX 1.3).
- When the Fighter Fly (npc-54) is set to "Don't Move", it still moves. Weirdly enough, it also chases the player when set "Don't move".
Please adjust the following speeds to match 1.3 physics. (Don't worry, these values are exact.)
- Set Fighter's Fly x-speed to 1.4 and -1.4 respectively
- Set Mega Mole x-speed to 1.8 and -1.8 respectively
- Fireball (Physics for Mario):
- In SMBX 1.3, when the player is still throws a fireball, it's generated with the x-speed of 5 (and -5 respectively). If the player throws the fireball with "Up" key pressed, it's generated with the speed of 4.5.
- When the fireball bounces set its y-speed to -5 (in SMBX 1.4 its -3.5)
- In SMBX 1.3 fireballs could never have a x-speed under 3.2 (and -3.2 respectively). Currently in SMBX 1.4.5 when you're skidding and throw a fireball, it can be generated at a very low speed.
- In SMBX 1.3, when the player is still throws a fireball, it's generated with the x-speed of 5 (and -5 respectively). If the player throws the fireball with "Up" key pressed, it's generated with the speed of 4.5.
- In the case of ice balls, I'll only suggest setting them a minimum speed of 3 and -3, to avoid odd things like this:
- Spoiler


- Set Venus Fire Trap's fireball (npc-246) travelling speed to 3.
