Loved the graphics that you make, It looks really good. the gameplay itself is quite fun, an endless runner with a recurring boss and shooting mechanics. but there's a little bug on the jumping mechanics and the tutorial. when you spam jump, it will register the jump twice(or more) and make the player jump really high(and I abuse it to go further :D). and the second is the Tutorial, I can drag the Image that was used in the tutorial to the left/right but on the right/left of it is just black. I assume you want to make the player able to slide the image to look at the next part of the tutorial (or maybe not and it's just a bug) so I went back and forth between the menu and tutorial until I realize I have to click the circle :). Overall a really good game.
