WASD or arrow keys. Check out @colinmacc's original project Headlong Maze (100 Block Games Challenge): https://scratch.mit.edu/projects/758131450 I love the 100 Block Games Challenge, and started thinking how I might make such a project. Although this has less blocks (25) than the original project (97), it's also much less fancy (with no ball trail, shaking, etc.). All of the 25 blocks of code are in the Player sprite. All code in this remix by me (@kriblo).
