arrow keys to move. change the "minimap" slider to 1 if you wish to see the map and player. a quick note: moving outside of the boundaries of the map makes the project lag
this is a raycaster that I programmed FULLY BY MYSELF. no tutorials here. not even griffpatch. just my little brain. it still has the fisheye effect, so in the words of other programmers it's not "mathematically correct". also, it's really basic. there's no other color than red except for the fog in the distance. plus any ray outside of the fog limit just won't be drawn at all. this is the first time i built something like a raycaster entirely by myself. of course, it's still far from using pure C and OpenGL to make a raycaster which is much harder, but i'm still proud of it. i hope i'll be able to switch to more low-level, and compiled programming languages like C, C++, and Rust soon instead of using only Scratch. making these projects is fun, but everyone pretty much knows by now that handwritten code is superior to Scratch's basic blocks, being able to expand the limits of what is possible and sometimes create bigger feats of technology (as long as you don't screw up memory management, of course.)
