Thank you for the feedback, we did try our best to tidy up the 3d platforming controls and that sort of thing definitely could use a lot of time perfecting, unfortunately we were on limited time so "acceptable" was where we had to call it good enough for now.
As for block colors we did actually make blocks different color to discern their purpose. Green is static, blue moves with your power, brown blocks are mechanism activated etc. If we had more time though it definitely may have benefited us to more explicitly point this out.
The power plug sprite is also something I personality agonized over a lot to see how exactly to show that fire would equal power for it haha.
More levels definitely would've been awesome but unfortunately we ran out of time so we instead opted to hella polish the few levels we did have as well as possible. If we do a post jam version though you can expect to see the concept much more realized with more levels!
