The idea of not being able to move backwards is actually interesting and would be curious to see the game developed further to see in what ways that could help/hinder the player.
However the lack of movement on the background when moving made it really weird in my brain to track my movement properly.
But it’s a game jam, and as you’ve said you didn’t have a lot of time, so with that in mind, things like this are understandable, nice work.
