I ran this game and it did nothing.
Edit: Tried again the next day, game worked. No idea why. Fought and completed the first boss on wave 10.
I love the art for the enemies and the protagonist, and all the attack at play. My favorite was throwing the sword. You might want to explain controls in game somehow.
I'm not sure why the default speed is not running. There seems to be little to no reason to walk, and holding down shift forever is a pain. I also would like controls that force me to contort my left hand less often. It's hard to spam sword throwing and move right at the same time. Use right click? Spacebar? It would not be a problem if I was not spamming attacks constantly, but this is that kind of game. Custom controls would go a long way.
Obviously this game needs background graphics, better enemy variets, more SFX, but I liked the pieces that were here. Especially the graphics and the boss battle. The way the trash can enemies acted worked well with the player's abilities.
