This has a lot of potential! I would add more variety with some more enemies and upgrades, also I would definitely zoom out the camera more, right now when you see an asteroid on camera you have got too little time to dodge them, also the controls are a bit janky, A and D don't seem to do much for me, but maybe I just needed more upgrades.
Btw idk if it is known bug, but upgrading your ship resets it (no more missile launcher and propulsion).
I would like to see this developed further!
Thanks for playing and reviewing! We do have 4 enemy types but they're uncommon to see since they spawn in after a few minutes of survival. A & D are really slow, but upgrading rockets does help that significantly.
I agree with you that the camera should get wider as the starship grows.
The upgrade resetting the ship wasn't really a bug, it was more to allow re-imagining the design with a new shape, but we agree, it probably could have saved the existing configuration.
Thanks for your feedback!
