Really great concept. The idea kinda reminds me of the SM64 iceberg, and the idea of the personalization AI in some way. The way assets from other games in the library where put into games that play, feel, and look completely different from its original purpose is an intriguing concept, and could be explored even more.
Also, the visuals. Very faithful to the graphics of the PSX and N64 NS64.
Overall, I nice game that could be greatly expanded upon.
