I really dig the style of your game, just wanted to give some feedback
- I couldn't figure out why you would use the spin attack, didn't seem as useful as just shooting, looked neat though.
- From the screenshots it looked like there was more to the game than the first screen. Maybe there is, but I had no idea how to progress.
- I figured (at least I think I did) that the diamonds were breaking the tree looking cubes (the things that are obstacles) so I assumed that I was supposed to do that to move on, but nothing seemed to happen once I got rid of them all.
- There was also no visual feedback that the tree things were getting damaged, so I couldn't tell if they were just disappearing on their own, or if I was actually getting the enemies to destroy them.
- I have no clue what the paper airplane looking things are supposed to be, or do.
- Also when I finished dealing with everything, I got confuzed and just started moving around the screen without a care for what happened to my character, then the game froze up. I'm assuming you're using GameMaker, and it seemed like the game got stuck in a while loop or something like that. Since there was no error report, and the game became completely unresponsive.
Keep up the work.
