Hi! This is a small project that I always wanted to make. WASD to move SPACE to shoot It consists of an algorithm that solves the problem of detecting collisions at high speed using the common 'repeat until touching: move steps' algorithm, which usually isn't useful since it ignores the large gap between the previous position and the next one. Now, with this algorithm, you can detect collisions at incredibly high speeds. Compare my algorithm with the normal one by toggling the 'algorithm' slider. I've added different sounds for collisions with the map and collisions with the border, so you can better distinguish whether it passed through the walls or not.
