I've been working on remaking all of Ben Bryant's Cheapo's levelset [sg1 and preview sg2]. The levels included in ROTL will be in here as well. This is what's finished so far, I'm still working on the rest. If anyone else wants to contribute, you're welcomed to.
Solutions to all levels. A couple of these may be backroutes.
I've redone the level Barricaded (aka Evacuation) in its original marble style and provided a replay. The only difference to the easier repeat (Evacuation) is the save requirement is 195.
I've also attached Metalland with a minor change to make it closer to the original. Proxima has a variant of the solution which is essentially the same thing.
