I never know what to expect out of an ending screen. Maybe I want more levels? Maybe some kind of additional satisfaction? I'm really unsure.
Anyway, it seemed fair but tense and rough by the end of the game. It was definitely fun. I kept getting confused about which way the space gun aimed. I think it could have used more upgrades, like tighter gun rotation, faster robot movement, faster item generation speed, etc. Like if there was a little tier system you could spend points on instead of just the raw materials.
Well it felt easy at first but it was a pain in the butt to beat. Is that good? I think so. Overall, I'm happy.
