Thanks for feedback.
The trail is there to add the need of some extra thought before acting. It's not explored enough tho. One note on dying, there is a slight delay before dying (you are able to pull out before dying) and the levels are quite short. I see it can feel frustrating. That part is partially for speedruners to hinder their time.
As for the glitches, I have no other defence nor explanation except: It's gamejam game. Sorry for inconvenience
