1.5 days is really impressive! Art wise I really like the minimalist black and white, the cat is very cute! Gameplay wise I think the game was fun, but a little bit too difficult, especially in level two I had it were I died a bunch on the jumping over the white symbols, it might help to have some kind of checkpoint or a slightly easier mode where a player does not lose the coins they have already collected? :) Also, definitely make clear when the player has the coins they need to collect and that they can move on, luckily you had it in the description but otherwise I would have almost missed that there was more level than one! Super well done on your jam entry :)
