Thank you for the feedback! The reason it snap rotates is because I made it in scratch, so doing all that math would have killed me, making it snap made it much simpler.
Thank you I appreciate the feedback. Also the quarantine symbol is supposed to get rid of the source, meaning if you don't use it, there's a high chance it will start again in the same area. And yes the walls didn't exactly work as intended.
I like the theme interpretation! Just one thing that bothered me a little: you mixed different art-styles together. If you use pixel art for the character, use pixel text as well. Also this is no biggy but the player can go through the walls after you complete the level and the transitions are a bit slow for my liking.
