Character is cute, but overall the levels all started to feel the same because there was not to much variety, and it was all just follow one path to get to the end. It would be nice if a couple of levels had multiple paths potentially. Like a path with fast hammers that's quick to complete the level and one that is a bit longer with slower hammers to give players a little choice. My other recommendation would be to add some sort of collectable in each level and then have made the last level unlock if you collect them all to let players feel like they completed the game and the last gauntlet is a bonus. I personally did not complete the last level because the floaty controls made the game a bit too slow and losing a long level feels worse because of it. Sorry if it seems like a lot of criticism just want to see you and your games improve! I did enjoy it overall and I hope you continue to make awesome games!
