Feedback:
Good:
1. You do have a level select that lets you play certain things
2. The shooting recoil feels good
3. No microtransactions imagine XD
Things to fix:
1. 
If you can fix that it would look better on some levels
2. Level 12 to hard the shot to the key is frustrating
3. Maybe make the bocks you shoot indicate you have to shoot them
That's all I could find when playing the game
