I can see how some of the bugs can be helpful. There was a few times I landed on a wall like a floor and was able to make a jump that way. I can appreciate intentional jank when it's in my favor, haha.
With the opposite direction thing, there was a moment I was on the floor and the arrow was pointing left, but when I launched, I went right instead. What I think might have happened was the game misread the floor collision as wall collision and bounced me the opposite direction I was aiming. I tried doing another quick run of the game to see if I could recreate it but I wasn't able to. Either I misread or misremembered the situation or it was just some obscure collision fluke I encountered.
And yeah, I would love to play a version with more trash! The more trash, the better :)
