Really like the elemental enemies, you got a great idea! Not too familiar with the game gendra, so I lost health with the early waves already haha
But maybe with some perseverance I can beat that game :P
I do think I made the levels a bit too hard. I didn't have much time for game balance as I focused on polishing the game/getting rid of bugs and making the game complete that I forgot about what's important xD
But I was able to get to wave 15 without losing any lives after I got used to it so hopefully, it wasn't too hard. Glad you enjoyed it!
