Thanks for the feedback! The bug on the fourth screen was actually a known issue that we were only able to fix after the deadline for the submission, unfortunately. The bug later on is probably caused by bad checkpoint hitbox placement, which I'll look into. Also, if we didn't run out of time, we definitely would've created in-game directions and controls.
I do see where you're coming from about the brightness, as I think we were hyper-fixated on the few light sources that some parts of our game may be left in the dark.
Again, thanks for playing and giving us your thoughts.
