[Request] Power-up Stacking

[xxxzzz1]

If someone could make a script so instead of collecting power ups they stack together, like in Metroid, so if you collect the fire flower you will never lose it even if you are hit.

for example, if you collect the leaf while you have the flower, you keep the fire power AND can use the power of the leaf and same applies for any other power you collect from that moment on, hammer suit, tanoki etc. Im planning on making a Super Metroid based project.
