I like the art style, the first level is very warming and welcoming. The mechanics and controls being introduced were well done too. Though I was dumb and didn't realize about the "slam down" mechanic for a bit. The character animations were well done. Having a ledge grab animation is really well done and I didn't expect that. I found the difficulty a bit too much but I am terrible at platformers.
Funny enough I found a small bug from the main menu. If you click the start button a couple of times quickly it plays the background music for each time you click it.
Nice job well done!
