It took me a minute to get used to the control scheme, but it was smooth sailing after that.
The music fits this game perfectly. It sounds so, "The Future is 1999". And, putting the health bar right up the player's back was a great way to give them the information they need without HUD clutter.
After a few tries, I made it to the big blue boy with the hammer, but he turned me inside out right quick. It's great that you can interrupt enemy attacks with your own, and that sword slash projectile looks real nice.
If I could make two small suggestions:
1. You might want to put a collider on the portal for dummies like me. I thought at first that I was supposed to walk into it, but I just moved right through it and fell to my death.
2. I think it would be a bit more intuitive if the player moved relative to the camera instead of their own facing direction. The tank-style controls are a bit mind-melty.
I'm always so blown away by 3D games. Did you make this on your own?
