I came from your challenge post and I’m not sure what should I say about this. The idea might be good (for the theme?) but your level definitely needs more careful design. If it is going to be used 5 times differently, you want the level to be fun.
One thing I have noticed is the jump height of the elephant is not consistent (without a mushroom), which will break your level (e.g., in the 1st run, I simply jumped to the door without getting the mushroom). I am not sure if it is intended or not.
Also, do players required to enter some kind of code in the menu to beat the game? I couldn’t figure it out …
Overall nice try but maybe it needs more design. I like the MSPaint graphics! o/
