A new take on a tower defence game - I like it. I did find the controls a little tricky and would have preferred to have an option other than z for sword attack. I think it would probably be better to not charge people coins for the arrow attack either as I struggled to actually get enough coins to build a tower, which I think is the key feature/mechanic of your game. I enjoyed the scene and the setting, I thought you had a really cool collection of enemies with different abilities that were well thought out, and the core mechanics of the game were really solid. This is really an enjoyable little experience that I think you could keep developing on. Good job.
