Hahaha pretty cool game, I first tried staying alive just by chilling on a block but that didn't get me far. My next run I just use my tongue and I got to say the fun level just went up! swinging from block to block like spiderman hahaha! Could probably even make it into a puzzle survivor game, maybe there's a door above that you have to use your tongue to get to, and perhaps some blocks wouldn't fall and you wouldn't be able to go higher so you'll have to use your tongue to toss the fruit to it .. or something like that >_<" hahaha, anyways, well done!
edit: Oh forgotten 1 thing, adding just a simple instruction on the controls would be good too especially in a game jam where there's so many other games with different controls.
