This I spent some time on. But i got 3 giant rooms back to back and it was repetitive at that point.
Gave it a fair go.
The game is really good conceptually, it's just these type of games tend to need content. Having 1 or 2 enemies and 1 or 2 room types gets boring. You did great with the time you had, I just would urge you pursue this game further with more time at your hands.
Visuals: Looked great. The enemy design is sick.
Audio: Simple and not intrusive.
Gameplay: A real fun one just needs more content and abilities for the player. I'm imagining a Binding of Isaac item system where you just keep building up a better sword that gets ridiculous later on.
Feel free to play my game too if you can. I'd appreciate it alot.
