One of my favorite games of the jam! You've managed to make something addictive and enjoyable inside of such a constrained medium.
I love that you gave me a simple tutorial / scratch space to learn how to control the player before giving me a challenge. The game has crisp and precise controls, so it feels good to do the challenges.
I also like how there is an element of strategy to picking up items. It's riskier to pick up items on the periphery of the screen as rollers can get you without warning. So you have to plan more carefully before you venture out and collect them. That's really interesting!
