I really like the comicbook aesthetic you have going on here. IMO, the blocks and the background should be more contrasting colors... red on red doesn't look that great.

My first issue is controls... at first I tried to swipe rather than just hold and move. A tutorial overlay in the beginning might be nice.
Also, I really want the sounds... I know that will come later, but it looks pretty good, I just wish it sounded good.

I will admit I didn't get very far, but I hope / want to see power ups... maybe screen shakes? other "juicy" things in the game.

Great suggestions. I plan on doing an iOS release someday. No plans for standalones yet, but maybe someday.

Let me start by saying, I like this game. I have a bunch of opinions here, so take them or leave them.

Main menu UI is a bit busy and takes some getting used to. Maybe have a few sub menus, like a hanger... honestly, if you could get the number of buttons down to 10, that would be an improvement (may have to do some nesting).
When I middle click to emote, I shouldn't have to be directly on the button, but pointing in the direction of it. same with heal menus.
Using the mouse wheel might be a nice way to switch weapons.
Want things I destroy to explode / leave pieces behind rather than shrink.
Recoil was a nice touch on firing. Consider camera shakes as well (just slight).
Shift should make me "sprint", space bar should be "ship special".
Minimap should probably be in bottom left or bottom right (per convention).

Great feedback! I myself am not an artist, so I take no offence to the art not being the best. Glad you liked it.

Thank you so much for saying so! Let me know if there is anything I can do to make it better, and tell every person you've ever met to download, play, and give me good reviews on Google Play, haha.
