Hi folks, occasional reader, first-time poster.

I've been hugely enjoying the nostalgic fix with a twist provided by Neo Lemmix, and have progressed through almost all the ONML levels, but I've got stuck on Havoc 14. The problem is in the top left - firstly, the lemming misses the gap he's supposed to fall into from the trapdoor (no big deal, admittedly), but then when it comes to bashing his way out of the second obstacle, he doesn't stop like he's supposed to in traditional versions if you get the timing right. No matter where I bash from, he continues bashing into the next bit of wall.

Is there a way of fixing this?
