interesting... yeah, hardware-specific issues seem difficult to solve. i haven't had to deal with any yet myself, so i don't even know how to start figuring out that kinda thing. i'll try and give it another shot!
EDIT: i beat it now! i didn't realize everything switched back on its own when the meter filled up--i thought you had to manually switch it every time. i think if you could communicate that better in-game, things would be more intuitive. maybe the graphics could change, for example, between water and lava depending on whether they're switched or not. once i understood how the switch worked, the rest of the game made so much more sense. like the wait timer: it's the amount of time things stay switched, not just pointless waiting. and the only time i really noticed the wait was on that first part, when the spikes and the water are right next to each other. i managed to get through the rest of the game without standing in one place for too long.
a couple more critiques: one of the later levels (think between the boxes) looked really tricky and i was having trouble figuring it out, until i fell down a pit and happened to land on the statue. watch out for this kind of thing! i'm not sure if that's what i was supposed to do, but it felt like i skipped the challenge on accident. the moving platforms also behave weirdly, in that the horizontal ones don't carry you with them. this is a tricky thing to get right, and i don't blame you for focusing on other things. if you're looking to keep working on this though, there are plenty of video tutorials on exactly this issue, because it's actually a very common problem for people who are starting to make platformers!
this was a fun little game once i knew what to do with the switches, and it had a good amount of levels for a jam! i liked the fakeout ending, too :) i hope you keep developing, even if it's not this project! again, your ideas are great and you'll get more of an intuition for the trickier stuff as you make more games.
