Great idea. I think a time limit per level and a minimum number of tags per level would make it more interesting/fun, also, having more than basic information listed at the start.
Gunbots are a bit overpowered, but awesome :D
Would love to be able to play as the necros.
Overall very very good. You put a lot of hard work into this and it's an excellent game
The spells need a bit of balancing. Terraforming is by far the most powerful things. You can kill enemy heroes with it, destroy enemy towns, etc. The other spells are too expensive to be practical.
Would also be cool if you could control units, but that might get too micro-managey and take the fun out of it.
Overall great game. Sandbox mode//additional missions would be stellar
Not too bad. I like the frequent checkpoints which keeps up the momentum of the game. Graphics are pretty good. Definitely could see some good work coming out of this
Cebolla makes things mad easy, and makes the game more time consuming than difficult
For first few levels, heal and attack. Don't use slow, it's relatively worthless at lower levels
For final boss (little big cup phantom dude) get the level 24 skill, cast reinforcements, then wait for your health to become very low, then use health switch. Dude dodges a lot, but if you waited long enough you should only need 1 or 2 attacks.
