Thanks for playing and for taking your time to write some detailed feedback! :D
Unfortunately, we were in a bit of a last minute rush fixing bugs so we didn't have time to implement anything other than a hacky restart by pressing R sort of thing. :p
We'll definitely add a proper game over screen in the future! ^^
As for the clarity and UI stuff, yeah, that makes sense. We'll fix those in the future!
And ooh, that would be cool Early on we had the idea of having environmental effects, but we ended up forgoing that due to time restraints. Maybe we'll circle back to that in the future! :)
