sadly i dont know the original but it looks like a cool concept. i noticed that i can sometimes walk throught the green line and sometimes i cant. Is that intended?
Youre using some extension to make the sprite walls, which might not work very well with scaling. I think you should just use the default tilemap walls. (And dont forget do make the projectile ghost through walls!)
The deltarune recreations are always sooooo coool! I like the first attack so far, It works well, I think I might have more feedback once more attacks are in the game though. Can’t wait to see how the art turns out too!
