This is a really neat concept. A somewhat cursed retro platformer in PS1 (or fantasy SBIGBox console) style. It's a pretty competent platformer, too, with fairly smooth movement and a variety of movement mechanics. The graphics and overall design definitely fit the SBIG style, though there's an issue with them I'll get into in a bit.
I love the addition of the manual, although it did make me a bit worried that the game would be super complicated that wasn't the case. It was actually really intuitive!
I really enjoyed the first level- the only complaint I have is that I missed the jump to the second elevator and had to redo half the jumping to get back to where I was. I do feel the game overstays its welcome a bit, though. I'm not super big on platformers, so it was getting a bit repetitive and the frustration factor is higher on the second level. Even still, I was willing to keep going if the game didn't start literally giving me a headache. Part of that is the visual style, with huge swaths of bright solid colours. It's hilarious at first, but after a while starts to hurt your eyes.
The other issue is that the game runs like absolute hot garbage. The framerate is not great, it's not so bad that you consciously realize it so much but enough for it to feel off and for me to go "wow, this is so smooth" when going back to a text box to write out my reply. On top of that, there were occasional stutters in the first level where the game would just stop responding for several seconds. I'm not sure if this is a WebGL issue or something else, but if it's the former I really wonder if a downloadable version would have been better. I'm hardly on a slow machine, so I wouldn't expect a game that looks like this to run this badly.
I'm not sure about the modifier implementation. I really liked the sound design, but I don't know if I would consider it excessive. The musical intro is super cool, though.
