Interesting interpretation of the theme! A few suggestions:
- Make the aim pointer bigger & brighter, right now it just blends with the environment & it becomes hard to aim
- I realized you can just click as fast as you can, unleashing an almost continuous stream of fireballs, - this makes the game too easy, maybe there should be a cooldown period before you can fire again?
- Explosions are too big, they make it hard to understand where’s the enemy and whether you killed him or not
- There probably should be at least some pointer to your finish location, otherwise you just keep aimlessly exploring the labyrinth
- It would be nice to have some variety in enemies & level design
Anyways, managed to finish the game (I hope that green room is the finish?), good job!
