it's a fun game! got a score of 2285
however it could use some more polish, such as more feedback when an enemy gets hit, or you finish a loop
however, it felt a bit weird at times:
for one, the enemies could for some reason just go through the walls that the black marker was supposed to draw
two, a lot of the times it felt like my loop just disappeared and didn't deal any damage for some reason, i'm guessing it has something to do with how you're detecting loops, and i sometimes (like when a bit too close to the castle i guess?) couldn't draw the loop which felt very annoying
also having to move your mouse to switch between the marker and the pencil was kind of annoying, i'd say bind it to a hotkey
overall tho, i really liked it! it's a simple but fun game
