Some neat ideas here and an interesting take on the theme! I like the ideas of the shop and the time you have decreasing as you replay. For constructive feedback, it could probably use some of that platformer juice, including things like coyote time, and I think the game could use some some sort of final goal/upgrade beyond the dash as a goal to work towards. Also I agree with other commenters that the dash was uncontrollable but lowkey it was also very fun to spam it and suddenly be half across the level lol
