It was a fun game to play.
At some point (probably wave 3 or 4) there started to be too many enemies and it started to become a bit too overwhelming but I managed to survive all the way to wave 10 but then when all the enemies where killed there wasn't a you win screen or something like that so I jumped into the hole.
I used the starting spell all the way through since it felt the most powerful with the ability to hit multiple enemies.
