OMG YOU FOUND MY GAME!!!
Thank you for the juicy criticisms. One of the struggles I'm facing at the moment is balancing the game, so your thoughts on the contrast between levels 1 and 2 are gonna come in VERY handy. I'll be making the stat increases less steep in the upcoming update.
As for combat and movement speed, I did get feedback about that from other play testers. I'm gonna try implement more features to speed things up. Should help accelerate my own play tests too haha.
The 0 HP bug. If it's not too much effort, could you send a screenshot of the stats and buffs of the attacking idol and the target enemy?
Once again thank you so much for checking out my game. :D
