Overall, the game was... good?
- The tutorial was very fun, but the boss fighting part was nothing similar to that. The platforming aspect of this game can be more dragged out.
- If you just want the game to be about boss fights, I would suggest just a difficulty menu where easy mode gives you less coins, and hard mode gives you more. I only suggest this because it was very overwhelming when I first saw the boss menu.
-Lastly, the sound effects when stepping on the shop or boss menu was, frightening? I was incredibly loud, and while wearing headphones, was LOUD!
It was a really good game, with lots a polish and it felt great, but the issues that I stated above are things you should look into.
