RPG Maker character getting banished to an 8-bit world? Sounds a tiny bit familiar.
In all seriousness, this is beautiful. Your art style is adorable. It's such a nice blend of retro graphics and clean lines and curves. The sound design is also really nice, especially the little beeps that vary in pitch when Harold talks. Really reminds me of Celeste. It really sucks that you could only get as far as you did; I would love to see this fleshed out into a full game even if dev time for the game is over. This is one of my favorite submissions so far and it's unfinished; imagine what the full game could be like!
