It's an interesting idea to give the player control over nothing but the special abilities of their party. But with cooldown being the only limitation, it really just boils down to spamming. The concept could be improved by adding some more resources to handle, so the player has to think carefully if using an ability is really worth it in the current situation.

I really love the presentation and colours and shading! It's so neat and the colours are bright and it's very clear and simple-looking! and the HUD's nice, too! It's awesome to see more 3D graphics like this!

I think this would do very well as a mobile game. It feels like a reverse tower defense game.

This has a ton of potential!
