I made this game in a week, tell me if you think the idea is worth turning into a game with enemies, more upgrades etc.
Click mouse to move player, gun follows the mouse as well. Avoid white plasma, collect gold for cash, red heals you. Space to pause/upgrade.
The game also tells you this.
So our advance outpost detects a vast army of enemy starships that are headed right for us. Scary, I know. But anyway we had some time so we spent 9.53 GTrillion space dollars on the bestest gun there is. It is sold gold and shoots deadly white plasma. There's just one problem it's so big that we can't see past it to aim it and we don't have a cent left to our names to install a camera. So you are going to test the feasibility of using a spaceship in front of the gun to aim it, good luck.
