I couldn't finish because I got stuck inside of one of the red blocks as it turned solid. It's also not clear where I'm supposed to go or what I'm supposed to do to get back to the start while the timer is going and you need to rush through it.

The toggled blocks are a bit janky atm aye, sorry I didn't have time to program in a little fix for when you get stuck.
Rushing through is intended, and the way back to the start is the same way you came. I will say this first demo is a little more challenging than a tutorial ought to be but that's mainly cause I didn't have time to seperate it into 2 levels that build off eachother.
I hope you'll try again if it ever strikes your fancy, and in any case look toward future updates. Feedback like this helps improve future versions!
