You have a very talented pixel artist - game looks lovely! Over all its a really neat idea - combine the elements to change slime's type, and each slime has different properties! Only gripe is that there seems to be a problem with jumping. Even as a "normal" slime, I found myself needing to spam the jump key, and it only seems to register every 4-5 presses. It is very inconsistent on when it wants to jump or when it doesnt. This happens when sitting still, on a flat piece of open ground, using a normal slime, after a couple minutes of gameplay. Either way, great entry, and a cool concept! Nice work team :)
