I uploaded a game that you choose your cubes by strategies to build your mech and fight in the arena.

It's been divided into 2 phase. 

In phase 1, basically you need to carry cubes from all 4 types. The cubes in the center area will affect the status of your mech.

In phase 2, try defeat enemies by shooting and dash.

The game is optimized for Android but I still got a Windows version there.

I'll be appreciate if you enjoy the game.
