This entire game seems fun... until the waves.
It's extremely finnicky and unreliable and serves more as annoying part of the game than a proper puzzle..
I think you're right, there seem to be issues with the wave's part, I recently got a 144hz screen and I can clearly see a difficulty difference between my old 60hz screen. I cant remember exactly how I had code that, but I think it's framerate depend (a delta-time issues to be techy), thats why some people complaining and others don't.
And from game design perspective, the whole game is about knowledge, you cant disarm the bomb first try, you have to make errors to learn and progress, the wave part, the cables, all of this are some kind of fillers/ time waster, not "real puzzles", I agreed with you.
Yeah, there's some... miscommunications that went in I think. English is somewhat of a second language. So do pardon me on that.
But, I mean, the concept around the game itself it is pretty nifty. There's 100s, and you aren't really expected to figure out you need the button/screws in the first run among other things. And when you screw up, it's clear that it's either on you for losing the tool along the way, or not able to realize what was needed.
But compared to them. There's no real thinking that goes into the wave thing. And more so straining your eyes on the right side of the screen after setting the height, and holding left click and drag along until it matches for 5 consecutive seconds or something. Doesn't help that it drains much faster than it gains too..
But yeah, That's rough. Well done concept all the same though
