Wow this is such a big game for a solo dev in just 4 days, and everything is great and satisfying! Though i have to leave a criticism.
The gameplay is a bit rough, sometimes the slowdown isnt slow enough and the hitbox feels way too large (but this issue mostly only for one level with the tight spaces and the first key) but still that level was hell to beat, and every other level was 1000% easier than that one.
Anyway this is probably the best game i found in this jam so far! You did an awesome job!
