Thank you for the feedback!
I've fixed up a few minor issues with the game (including the eraser's return time) in a small post-jam(ish) patch. Throwing the eraser was meant to be a bit risky, requiring the player to shift focuses between aiming and dodging, but I agreed that the eraser was taking too long to come back, making it much harder to keep the run alive.
Feel free to check it out when you get the chance! (^-^)
