Looks to be pretty bare bones atm, but I know you only started on this recently. (RIP card game)
I was able to mine the rocks and build a little army to destory the enemy, so core mechanics all seem to be working right.
Unit controls are a bit strange tbh. I much prefer the traditional drag box to select multiple units, right click on target style.
Found a glitch where if I selected the building I can spawn cats with, and then selected the enemy building I could spawn my cats with that building.
Good luck with the game!
