I enjoyed the idea behind this game, but here're some things that stopped me from playing any further:
- I think that the punishment for death is far too severe. It's enough that tougher enemies spawn and you lose a chance to fight equally matched opponents. To lose EXP on top of that is just frustrating and makes it far more difficult to fight next-day enemies.
- The game feels too decentralized. Wasn't sure what the point of it was after the tutorial. I got the impression that this is a survival game, but even then, some sense of direction would be nice.
- Although I like that you've added weight to the player's rotation, it's too unresponsive for a tight gameplay experience. Maybe reduce the easing factor so that the player rotates more quickly?
Anyways, again, I really like the idea behind this game. With some more polishing and a bit more depth, I would probably play it for a good amount of time :)
