Pretty good game, the death counter not having the post effect was a little weird, ONE THING i disliked was the fact that when you are upside down there is a different key for jumping. Music fit pretty well, the portal was a bit out of place being pixel art. A little more air control would be good especially at that spike fall part, the SFX were quite uh, interesting. The end of level 3 was annoying because of the spike hitbox. The reverse boxes were an interesting addition.
Overall it was a decent game but a lot of areas were quite annoyingly difficult due to the character movement or colliders.
