Yea, the game is pretty easy, which doesn't mean it's bad. I think the concept is very interesting though.
I like that there's a level of risk of shooting (which progresses the game) however, the meta is to just shoot right after he bounces off. I think once you figure that out, the game becomes very easy and formulaic.
Rage is cool but I think more could be added to its mechanic. It just goes faster now, but it doesn't really counter the strategy mentioned. Maybe it could go even faster or fire projectiles you have to avoid? I'm not sure.
Overall, I enjoy the aesthetics of the game. The vertical layout and easy to replay gameplay makes it also feel like a mobile game.
