@Armani, @IchoR1 - Both of your solutions are 100% intended. Nice job!
Not sure why I didn't think about those fixes sooner, especially that quicksand addition. I find it very interesting that Armani pretty much did the exact same thing I did in the first several seconds of the level, though that might had been because I leaked and attached my intended solution for him to compare when I called his solution acceptable several posts above
Anyway, hope you gentlemen liked it and that the timing with the climbers isn't too tight! I really tried to ease that part and made it as forgiving as much as I could!
R2 - Ah, you gentlemen play hard!
All right, I really could had avoided all that trouble from the very start by simply adding more OWAs in the area that keeps getting abused all because of the preassigned swimmer hatch, but I really thought I could get away with not needing to do so
Looks like I'm out of options now, and I was thinking of resorting to pickups, but let's try this first before I might need to. For V11, just more OWAs and also shifted the ones near the entrance up some more and also extended them.
edit: I noticed the R2 got 3 downloads, but I have reattached it as apparently the ones near the entrance needed to be extended too. That's what I get for thinking moving them upwards would be enough and not actually testing it to see if it blocks off Armani's really cheesy backroute
