This is a full on game! Think you just need your own visuals to make it your own. Congratulations! I think I suck at the game because I died a few times and one is getting the first boss down to 60% . All in all I had fun :D .
Something I would check:
- not sure if its intentional, but the last 20 seconds no one attacked me and I just waited there for the boss to arrive. If this is intentional maybe the last 20 seconds could be some weird effects signaling that the boss is on its way?
The UX seems very good. I understood (or at least think I did) everything that needed to be done.
Wanted to critique the Katana Slash ability. At the moment it only strikes at the player facing position which feels weird. Maybe the intention is to have it that way, but think it would be more interesting if it could point in the mouse direction.
