Thanks for playing!
I'll be the first to admit that the balancing on this game was a total nightmare. After my first round of playtesting, my players told me the game was way too easy even by just spamming random skills, so I played with the enemy spawns to try to make it harder. The problem was that even small things (such as adding 1 hp to enemy spawns) had such ridiculous effects on difficulty that it was really easy to accidentally make the game unfair.
You can definitely get a higher win rate with good strategy, but sometimes the game really does screw you over by not giving you what you need for a few turns. Even with my method, I only won about 3/4 games, which was okay but admittedly far from perfect.
