This looks really good considering that it was made in 2 days. I encountered a couple of bugs, which is expected with games this large, but here they are: 1- sometimes the hand gets stuck on walls and the floor, or jumps all over the place, making it hard to recover 2- in like the 5th room, i launched the heart, it didn't hit anything, but it wouldn't come back. I tried walking to it but i couldn't pick it up, and i had to keep going without it (i didn't die because of this) 3- when you kill enemies, their sounds keep playing, and sometimes projectiles still get shot even though the enemy itself is not there.
That's all, overall it's an impressively polished game and i hope you'll continue it post jam. Oh yeah, the animations are beautiful.
