OMG, 4:2x is finally done. The run is still full of small mistakes, but overall its pretty good. I had been going for runs without the boulderless strat in 5, but this was my second run of the session (first one to get to lvl 5) and I just forgot that I wasn't going for it. But it paid off as I pulled it off, then played decently enough to barely clutch 4:2x. Level 6 really sucks I was so close to saving like 3 secs.
4:1x is definitely realistic but I'm taking a break for now and going to move on to other worlds. If you take this run, do the faster boulderless strat in 5, make the wall jumps in 6, don't clip the corner at the end of 7, do the fast strat in 10, get a better boulder boost in 12 and beat the boss faster, you could barely make 4:1x
You are now allowed to submit runs done on the official WebGL Unity version of the game, which can be found here:
There is currently no speed challenge mode available for this version, which means you cannot submit
