This is really my kind of game! Some feedback:
- I think the screen transitions could be more instantaneous
- Sometimes it feels the input is missed. Not sure if you're doing any input buffering or if my keyboard is just too old, but some more input buffering may help it a lot
- I think it could be more forgiving. Like if you drop 5 charges then half or more appear in the room the next time you play. Or maybe you don't die 1st time but just drop things
Overall, great game! Top marks
