Thank you! Game is actually balanced (mostly) but the problem is that I expect player to have my level of strategy knowledge. If it was full game the difficulty curve would be stretched so player wouldn't get overwhelmed.
Here's some tricks I use
- Never use spells until no enemy will attack you (expect if formation of enemy will be scattered)
- Sometimes sacrifice health to get most of the spells
- Use fire to kill archers, ice to slow down tanks, lighting to kill lone enemies in lane, and metal bullet to balance out the field
