Oh hell yes. I've been looking for a RPG like this. I just discovered your game and played it for 2 hours straight. What time is it? 6 AM! Well.
What you could do, though, you can add more items, more maps, a skill tree, more attack options (I really liked the sliding, though. That was just straight awesome.) Maybe a foot flaming backflip hit would be great? And you can add enhanced movement. You added ledge grabs, that was great. Sprinting, rolling would also things I'd like to see.
Awesome game. 5 stars. Lacked some items. I was gonna give it 4.5, but hell, it's great.
