Awesome game and really impressive! Completed the game and had a really good laugh at the end. Banger tunes, a really great gameplay loop, and funny humor make this into a game I'll replay at some point.
I did play this through Mupen64Plus-Next on RetroArch and the levels ended up being black and white sadly. The screenshots on the page look great. Also from a gameplay standpoint, I found it frustrating when I dropped an item infront of the portal and it ended up missing, or when I needed an item but the tables were loaded with unique items and having to run back and forth frantically to empty the queue.
