This is really good! I love the graphics, the idea is really cool and the implementation works great as a proof of concept, although I do think it needs a bit more polishing for a future release. The keyboard controls were really janky, and I loved it! Felt very authentic to the PS1, even if I was playing on a keyboard. I would like the inclusion of a more "modern" control scheme as an option, though. The biggest issue for me was the music, it was honestly a bit annoying and it didn't help that it looped so frequently. The puzzles need a bit of work, but overall, this is a great entry! I love the transition between worlds and the effects are awesome!
