Alright ! Tested out the game. I like the play area idea with the gauge, but I feel it is still lacking a bit of something... I know it's hard to do more than that in the amount of time but I would have love the to see some bonuses pickup appearing here and there to make you take some risk for more points. Or even have something that lock the zone for some time. Some little arcade thing would be really nice and I feel the game could have a lot more depth with that ! Also I have some trouble with the controls where it takes time for your character to start moving and stop moving. Maybe gravity and sensitivity needs a little tweak in the input settings of unity ? Also maybe it was meant to be this way but I can't move if I first press the spacebar and then try to move. If it's volunteer maybe some feedback, like the character changing color, would be nice for the player to understand he is stuck
That being said I have to say the execution is pretty nice, I love the HUD, I love the music a lot, and I love the idea of the game. It inspires me !
Anyway all I said is meant in a constructive way I hope you'll find it nice and helpful !
