Thank you! I'm glad you liked it!
Regarding the characters: yes, they're filtered right now. In my first upload I forgot to unfilter it, thankfully I was reminded by one of the earlier commenters. When I unfiltered it however, I realized that it messed up the outlines I placed on the characters. It also didn't match the background anymore, so I reversed my decision and filtered the characters again. Maybe in future iterations I'll fix the character sprites to mesh with the background better, even when unfiltered :)
The character sprite in the main menu is unfiltered though!
