I don't think the idea works too well, not being able to move most of the time is not so good. You can pretty must just roll until you get the sword and then spin around rapidly without ever rolling again.

Also it should be visible what number you rolled in my opinion when you put it on a D20 like that.

This has a lot of potential, I can imagine an awesome soundtrack and some gameplay tweaks this being a ton of fun. A few notes from my game. I didn't have a clear objective, so I assumed I should just survive as long as possible. Perhaps displaying a timer counting up would help reinforce that if that's the case, so I can track how well I do between runs. Also, I backed myself up into a corner and it was pretty easy to flail the sword around so I didn't have much incentive to move around after that as I could kill anything near me quickly. Perhaps some enemies with ranged attacks would help push me out of the "safe" area, or have powerups/objectives spread around the level I need to go find.

Overall very fun! 

The idea and concept were really great. Great job!

Good execution of the concept: A random gear in an action arcade game! The concept is respected and the game works (Congrat!), thank you for the enjoyment time :)

And I really liked the little cute little enemies :)
