This was a really fun puzzle game and definitely unique for an RPG Maker game! It was challenging, but fun. I really liked the art style and overall retro feel of the game, ranging from the character "voices" to the custom art. The character drawings were well done and have a lot of personality to them. I loved the VHS-like filter effects that you added; they really added a lot to the retro feel you're going for!
That Easter egg you put in the shop of the RPG Maker 2000 poster was a nice touch that I wasn't expecting to see too :)
