Might have been better but still very good
The engine is great and there are many bugs, although it was entertaining
Sometimes battlefield was confusing, some enemy units can climb 3 levels at once, my units can't. Anyway they should be able to go two levels up
Battle system is quite dull, damage is always the same, attacking from either side doesn't change anything (actually I had better chance % to hit from the front!!).
Select squad screen was confusing, the order actually mattered, and sometimes even if I was suppose to be the attacking side, enemies stormed me on the first turn. Give them some more room, and let the player choose starting location.
The levels unlock themselves even if you play the same level twice, you can skip some with this. The story might have been a little more detailed and it should feature some reward, for example a new unit.
The points system was somehow bad, sometimes an easy battle would give me more, while very hard one would results in something like 80 pts. The classes are cool, but maybe the healer should have basic healling power already. And I would like a veteran system, that you can carry units that are better over to next missions
I would suggest to team up with some graphic artist, so it doesn't feel so generic (ie units, background)
Keep up the good work, I hope there will be a sequel!
