Fun mechanic, well presented - I loved how everything (the menu, tutorial, etc.) was part of the same scene, and the minimal geometry style was well realised :)
Alas, I was caught out by the few bugs you know about- 48 hours is never enough, and I see you got this in 45 seconds before the deadline, so my heart goes out to you there!
I did think it was a bit unforgiving at the start; the very first time you’re figuring stuff out you also only have one life so a mistake just kills you. Maybe start with a few lives as well?
