Pretty fun mining / shooting game.
I like the isometric style camera angle, and its quite impressive that you made a procedurally generated map complete with size choice and seed number :o
The movement shooting and mining felt fine, i just got a bit confused by 2 aspects :
1 : I thought i either had to upgrade to get guns or find another mech made for combat in the map to kill the enemies untill i realized it was way simpler, you shoot when outside of the mech and you mine when inside
2 : the resources indiation cost for the upgrades feel a bit confusing, i feel it could be clearer with maybe colored squares that correspond to the resource to be able to know at a quick glance how much of which is needed to purchase the upgrade.
Other than these 2 i didn’t have any other particular issue. The game was fun and i dig the mech’s look of being a cube rocking some shades B)
Good job ^^
