Those last two bolts are very hard, harder than the rest of the game by a lot. You can get the top bolt by making a series of very difficult jumps up the left side, or by tossing the core from the top right ledge and jumping to it.
There's a couple tricks with the movement that aren't necessary to beat the game, and we don't teach you explicitly but you might figure out yourself; If you throw the core downwards mid jump it gives you a little kick, enough to jump upwards 4 blocks. And you can use the core to climb walls, by picking it up and sticking it back into the wall under you mid jump.
I don't know what's screwing with your diagonal inputs, I vaguely remember a similar bug from another game jam... maybe it's a browser thing? I think there was something on some browser where it wouldn't let you hold multiple buttons at the same time, should work in Chrome. I forgot about that sorry!
Thanks for playing!
Ayyy!
I installed the windows version and the diagonal problem still seemed to persist, so it could very well just be my problem.
some keyboards have that issue, sadly, otherwise im unsure about the diagonal inputs! but yes, even with you completing it i take this input to heart! while personally i'm fond of the unclear way to go - (lorns lure style) most players struggled with this, i'll be trying in my future to improve flow and direction of levels so that it's easier to feel where to go next (and see things like which platforms you can and can't put the core better),
and as for the rods, while they were intended to be solved on a second playthrough after you learned some tech, or for less casual players, i did attempt to allow them to be completable without tricks, with the setback of needing to backtrack for them, even if it wasn't as clear how to do so- this could also be improved upon
thank you so much for playing and it's cool to see a 15 rod run with a decent time come out of it :)
if you were curious, i saw your original post and decided it'd be good practice for me to make a walkthrough video for the easiest and hardest paths for all rods, you seemed to enjoy the game, thanks again for playing and the feedback :)
