Hello! Here's some feedback on every aspect of your game:
1. The theme
The game really fits the theme nicely and while it is simple, i like the idea of the different upgrades you can choose from.
2. The gameplay
Unfortanetly, there are a few major issues with this game:
a) It is really hard to control. Sometimes i didn't know what was going on, also because of the points below.
b) The camera is too close up. Often i couldn't see anything around me.
c) The game is way too fast. The upgrades come too fast, i don't have any idea what's going on and there are way too many projectiles.
3. The Sound
The music is really calming and fits the game well, but it is completely covered with the projectile sound. That problem would be solved by making overall less projectiles and also only temporary upgrades though.
4. The graphics
There are some good graphics in this game, but the color scheme kinda ruins them. I would recommend sites like Coolors.co or adobe colors for choosing your scheme next time.
I hope my feedback helped you a bit. If you have some time, it would be nice if you checked out our submission too. Thanks! :)
