Great game! the controls the art and the music all work really well together to create a really fun experience, I like the idea of a roulette instead of a dice and the fact that you can choose whether you want to take a risk or play it safe
I think that your mechanic could be used not only for the amount and speed of the enemies but also to change your abilities and manipulate the way you move, it would've made this mechanic a lot more open.
Also respawn points would be a great touch aswell
Well done nonetheless!
