Glitches are never the intended solutions to any of my PoorTest Chambers

I got the moving cube on the pad PoorTest [028] but that's literally all I've been able to do. The only way I see myself progressing is with a glitch I have no idea how to replicate. Please tell me that's not the intended solution and I'm just missing something obvious?

I've been working on updating the entire series to fix things with it. I'll keep your note in mind, Thanks for playing!

I think PoorTest [018] might just be proken because I can't place portals on surfaces I globbed the white liquid on. Might make more notes as I continue. Also thanks for the advice.

Bounce gel and funnel placement is key. It is timed however, so be quick!

I've been enjoying your PoorTest series but I'm stuck on 013. How am I meant to get the crawling cube to the door?
