The movement is very floaty and the enemies and players both have too much health. I can't tell when I'm dealing/taking damage and the large health pools don't help.

But, that out of the way, this is impressive. The debug mode evidences a lot of experimentation with game engine basics, so I'm glad it was included. The asset use is also pretty good. Since this is more of a tech demo, then the prototype tileset is very appropriate.

Pretty impressive to start an engine from scratch. This may be an interesting option for another game with a little more time on the game itself.

The debug mode suprised me, thats a really cool thing imo!
