For just 2 people, this game has an incredible amount of content! Different equipment with abilities linked to them (the ability to roll forward was super cool to discover!), different tracks playing in every room (even though you didn't make the tracks themselves - still a cool detail I didn't see anyone else do!), and even the different equipment showing differently on the player model!
Very impressive stuff - I do agree with the rest that some polish is lacking (the UI buttons in the menu are a bit weird, the controls would've probably been a bit more fun if they were traditional wasd controls, the missing floor texture in the staircase room, the cubic block for a sword model, the burning particle effect...), but considering the amount of stuff you made in just a week with just 2 people - it's impressive enough as is, I'd say!
