Sorry for the hassle and thanks for posting these, they'll help making with a post-compo bug fix version.
Memo to self: there's another soft lock when you go to the bottom right corner in the second screenshot you posted.
Lovely graphics and animations! Got a bit confused about what background tiles the cart would collide with at first. Difficulty picks up considerably in level 2, there's a number of different obstacles and mechanics to manage and be decent at all of a sudden. The game is fairly short, though, so all in all, the challenge seems right.
Do you plan to continue working on this?
And have you thought of a multiplayer mode? While I was playing, I felt like the game would really lend itself well to multiplayer co-op, possibly without too much additional coding. Feels like it would be a ton of fun sharing this arcade experience with friends and family.
