Yeah, gears 1 and 2 are more an adventure mode thing, since eventually enemies will detect you based on your ship's thruster output. Automatic upgrades are going to go once I get the shop in. There actually is an option to disable the mouse controls and use the arrow keys to move, just not ingame atm. It emulates controller support, and that's not fully tested. As for shoot toggling, I'm not sure that's a great idea, but I'll consider it. Thanks for your feedback!
