I think the top upgrades are arms attack strength (for fighting bosses), bottom left is auto economy, and the bottom right is walking speed. I like the dual screen, the music was very cool. SFX was cool, nice steam and mech sounds. kinda long, I played for like 10 mins and was only half way done, just to do the same thing. could be a nice mind rot clicker game with more upgrades and maybe a prestige option.
