The visuals are pretty decent. I like the creativity and how the unique the game is. But some of the levels did get me frustrated quite a lot. The levels and the bosses can feel unfair and frustrating, although it could be my skill issue (giving little chance to react to the bosses and also dying repeatedly). The game focuses on a lot on trail and error, and also adapting the gameplay (took me a lot of deaths to pass some of the levels).
It's a demo anyways, so there is room for improvement. Overall, I like the game, and I'll continue to support it, and your YT channel.
