First up, if you are reading this wow this is a dead speedrunning community. So here's the actual guide. For hacked%, you would most of the time use this, https://scratch.mit.edu/projects/2322468/, or really any other one that allows you to not die. So because of this, we can do a lot of skips normally not possible. Since you can just wall jump through spikes, it seems like it would be easier to just press Up and left/right, to scale a wall, but it is easier if you bounce back and forth. An example of this is level 23, where it seems like the easiest way would just be to wall jump up the spikey wall, but if after the 4th or 5th jump, you switch to pressing left, you can hit the block on the left and knock off a second or 2. Also, there are a lot of level skips, as some level you can just walk over and fall through spikes to get to the end. Also (this goes for all speedruns) BE READY TO JUMP AT ALL TIMES. This is very important as I have found that random floor clips are VERY common, and will add time to your run unless you react fast enough. This is a bad Guide but hope it helped XD
