nice job, i didnt play it thru, but how do i upgrade? i kept dying
Good job tho. Highly rated.
It is a highly skill dependant game, you have to upgrade a lot your reflexes. Gameplay-wise, you upgrade on each tier, getting better lasers, better cooling system for lasergun and increased armour/health.
It doesn't contain a lot of the "Upgrade yourself!", I tried to but it was overscope for a single guy, so I kept just a few things out of the main concept.
