Thank you so much! I tried to focus a lot on polish and general "liveliness" in this game compared to others I've made before, so I'm glad that people feel that. I think I also did a lot better at designing levels for this one, but I think a lot of that came from the simplistic mechanic itself. (I personally love level 10 myself)
I think having all levels be accessible in any way is very important for a game jam, since unexpected behaviors are bound to happen, and you want your players to be able to keep playing your game. Which is also why I think skip buttons are also important. I know I've sometimes wanted to keep playing a jam game, but found one level too difficult to continue going.
