I was having enough trouble getting sub 270 on level 62 that I actually broke out the inequalities 50a+70b+80c+60d<=260 and a+2b+3c+d>=8, where a,b,c,d are the moves 1,2,3,4. It isn't too hard to exclude the cases with b=2 or 3. For b=1 the inequality is only satisfied with c=2, but this solution can be seen not to work by examining the starting position. Therefore b=0, and with just a little more work we find that c=2, which implies a=2 (and d=0). Having figured out the right attacks, it was just a matter of figuring out when and where to use them, which was frustratingly easy XD
Why must you present me with such hard speedrun strats!? I got 207 secs before I started finding any hard strats. This is gonna suck up too much of my time tomorrow.
I enjoyed this game a lot more than others I've played of the same type because of the additional mechanic of freezing your momentum. I feel like most of the people complaining about lag just didn't take the time to figure out the movement. That or the problem has been fixed. Movement was very good on controller.
You can jump while in the air if you do it right after teleporting. This lets you do level 12 without having to flip to the ceiling, so you can get the chests in the order top-left, top-right, bottom-right. You can also use it in level 13 to bypass the ghost, but I don't think it saves any time.
