I really loved the art style. Especially the little cloud shadows and the wind animation. The sound effects were decent too, but music would've made it even better of course. Sometimes it was a bit frustrating that going to the sides gave you a high risk of getting trapped by a wall of enemies on your side and a few in front of you. The controls were pretty smooth too. I really enjoyed it, even though it was a little short on gameplay.
Also, judging by your screenshots, the font wasn't properly included in my playthrough (Windows): https://imgur.com/a/UNqUpG7
