Hey man, I did my full 10-minute review during my Twitch Stream Friday night (twitch.tv/aaknox), but I'm going to summarize what I said during my review:
Art: I am a big fan of pixel art so no complaints there. The dust particle colors, however, may need to be a slightly whiter shade of the player to help distinguish where exactly the player's feet are on the platform.
Animations and Controls: Animations are very well-done, and the controls are very simple for anyone to pick up.
Sounds and Music: Overall, the music and sounds effect were perfect for the game.
Overall gameplay: Overall gameplay was fun but challenging. I had a blast the entire time as I navigated the puzzle. I would definitely recommend that you expand on this game for a bigger project in the future.
Hope this review helps you grow!
