Thanks for the response!
You've managed both level 6 & 7 much faster than I ever could, which is a little embarrassing on my behalf but congratulations on setting the unofficial record. As for patiently waiting on the platform to die, I'll just add spikes around the base or make the platform a lot smaller.
I too do a fair bit of climbing so I'll try and add more realistic grab mechanics based on what you've said and my personal experience. I don't know how quickly I can get an update out because I've had to start again but hopefully once it's done you'll like the changes.
