Great game! Really enjoyed playing it.
things I'd love to see :
Fast mode -> faster animations once I know what stuff does,
keyboard controls. Dragging with the mouse got old quick.
especially cause it's only a choice of left, right or up. seems like keyboard (or swiping -if you're targeting mobile- ) would be a great fit.
Very similar to this game on android

(except the direction being only forward)
hope the steam release goes well!
