It's really cool and polished when it comes to UI and the game HUB, loved the sounds and the store as well but the gameplay i felt kind of lost cuz it was realy hard.
Would suggest to make the bulles of the enemies a little slower and when you hit and enemy to give some visual feedback that the enemy took the damage, also would be cool to hold down the left mouse button and shoot instead of havind to tap it again and again.
Still pretty solid tho, congrats :D
