I enjoy the game environment and the character's attack animation. The game is a bit buggy and could use work, but I think I got the gist of the game. One cool suggestion for the stones is more unique abilities. For example, the green stone could change your sword to an axe with insane knockback (knockback kind of like an anime hero punching something sending it hundreds of feet).

While I wasn't entirely sure what to do, I did find the game incredibly fun. Despite the tank controls and a "S" key essentially breaking the camera, I got a lot of enjoyment from just running around and seeing what was around. I do wish the theme of "strange power-ups" was incorporated a bit better. I think letting you keep the magic stones abilities past just interacting with them once would help, and maybe introduce some more, since each one does essentially the same thing with a different color. 

One other issue I ran into was some super wonky collision. Of course, with a 3D game made in the span of a little more than a week, I'm sure it's a heck of a lot harder to test everything to get it right. For example, right at the edge of the town, there's an open gate so I went through it and ended up falling out of the world.

The game, at the end of the day, certainly needs a bit of work, however, I found it very enjoyable for what it is.

Not sure what to do. I wandered around for a while and killed one thing. The camera angle is not my favorite. Perhaps it's intentional game design but the jump height seems a bit ridiculous. You have a good starting point but it needs more direction.
