For the graphics, I was inspired by the Vectrex console that renders its graphics in vectors. I found it pretty cool so I made my game in a rendering style that emulates these types of vectors. I really had fun making these puzzles, so I'm glad you enjoyed it! I don't know if I will add something to stun the monster, I will have to thing about it for a bit. For the blocks, I noticed the illusion, I think I will fix it in an update.
Thanks for the review!
