Well done on all the art, the mechs and the fighting animations are pretty well done, and the UI as well is very slick. Was cool seeing all the different mech parts mashed together, ended up looking like a frankenstein-ed action figure.
I wish it wasn't an auto-battler and I got to have some more input on the fights, and it would especially be cool to have the different parts effect certain moves and what not, but I get that would require a lot of work and perhaps would go out of the scope of your original plans. Only bugged issue I ran into was that the mech piece descriptions would not always show so it could never really know what most of the pieces did, but it was still interesting trying to make high DPS combos for the mechs.
Good work overall though, nice looking game. Keep up the good work!
