I had some time to kill so I played some of those other levels, and yeah they're really cool!
- Snowstorm and Vector Field both had issues where I would respawn and then immediately die.
- Eternal never let me return back to the level select- I had to refresh the page to go back.
- Stars is another one that feels really cool but the acceleration felt off? I don't recall any (noticeable) acceleration on the other levels.
- That collision issue might be because of the instant restart. Godot tends to run physics and frames seperately, so if the frame isn't showing the latest physics where there is a collision, this might make it look off. Maybe like a hitstop death animation would fix it and add juice?
