Compared to Upgrade Complete! 1 & 2... This felt pretty bad. There wasn't anything new, it became a game of grab the heart, and overall felt bland. Maybe when there's an Upgrade Complete ! 4TheWin it'll be better.
To add in depth why this "game" deserves 1/5 stars: Controls are like flappy bird, you can spam up to infinitely fly. You do not die if you fall, and can fly back up. There is only one stage. No WASD support. Colors could seriously be reworked. Movement is as if the (Link from Zelda) is on ice and it slides a lot. There are no goals or even any reason to move.
People, please do not test your in-progress work on games on a public game site if you do not want actual responses.
It's a test game. Would rate 0/5 just for that.
But there are other reasons. WASD does nothing, arrow keys do nothing. Space bar does nothing. In short, this is a picture on the screen with odd music. Not a game.
Left and right are determined by where your ship is pointing. And it just turns you, not move you in that direction. Your bullets automatically have auto targeting. You can literally fly in a circle and kill almost everything.
While the game looks pretty, it's not that fun to play.
