This was a really tight platformer, not really the biggest fan of the dash, I guess with only WASD controls it can feel a bit clunky to manage, otherwise this was really cool and quite polished, great job!
Thank you! The dash was the last thing I added, and I couldn't polish it as much because it was messing with the character's deceleration. You could also use a gamepad if you have and feel like trying again :) The start button closes the upgrade window if you don't need to make changes.
