Sounds cool! In the style of "Mech Commander"
I think you made a good design choice by making the game isometric instead of plain 2d, especially for this type of game. Actually, what is
the type? Turn-based, RTS?
The player controls only one of three Mechs he chooses at the beginning of the game...
So in a 3vs3 battle, the player will only control one mech on his team with the remaining 5 being computer controlled? I'd personally prefer if you either had control over your team of mechs or you could issue "suggestive" commands to the AI like "Defend area", "Attack", "Destroy target" etc., but that's just me.
Let me know if you need some other kind of feedback and good luck with the project. Looking forward to seeing how it'll turn out
