Really great game! Loved the idea, the execution, and the challenge. My only nitpick was the marker hitbox felt pretty unforgiving. I would barely graze an edge and would die. Maybe it was intentional? It does add a bit of frustration, but even with frustration, I didn't care because the game was so satisfying and fun to wiggle through tight spaces that I didn't mind pushing through. Anyway, I was thoroughly impressed. Great job! I would love to see more!
