This is the first top-down platformer I've ever played, and I think it's quite well made.
There's an issue where the lower the level is, the laggier the game becomes, but that might just be an issue on my end and not really with the game itself. I also really liked how simple yet effective the obstacles are without doing anything flashy or pointless.
I am kind of at odds with the sliding thing the character does after you stop moving. It could work quite well with ice-themed levels or with a less "precise" kind of game, but here it's annoying and a slight but noticeable detriment to the gameplay. Maybe it could work here if it lasted just a fraction of a second.
