Just absolutely BRUTAL Level. A lot frame perfect timings and very hard bomb setups, this level was also very hard to perform. releaserate manipulations and tons brutal timings and just MEGA CUNNING

This level trouble is just there is no skills. One miner needed start. Just two miners have to go end. Two climber have to use end, basher will bash this under the trap field. 2 builder is minimal pass first gap. two goes next gap. Two goes end. So we have 6 blockers and 2 optional builder to pass this level. I no have any single idea how this level have to be pass, that was very hard saved even 5 lemmings

Present 16 - Nice one on saving so many more than required, but obviously a backroute - it shouldn't be possible to save more than 87.
Present 18 - Backroute, but I think you know that Any time you engage in pixel manipulation to pull off some seemingly impossible feat, you can be pretty sure it wasn't intended.
Present 20 - Exactly as intended!
Present 22 - Slight backroute due to the fact I didn't realize the far-right wall was already 6 pixels high and you could create a barrier with a single builder (which you could sacrifice since you didn't have to use the bomber). I'm happy to call it an alternative solution though as it's at least as good as the intended.
Present 24 - Acceptable solution More or less intended, just that I platform the second-highest little gap rather than the top one, but IIRC Guigui solved it the same way as you, so I guess that way of doing it must be more logical than mine.
Present 26 - Total backroute. Not a single element correct haha but well done for finding it through some insane shenanigans!
Present 28 - Another backroute - it's not supposed to be that straightforward!
Present 30 - Major backroute, with some elements correct (and very quickly deduced, well done!). The main backroute-y part is freeing the crowd with a basher from below. I thought I had already blocked this but apparently not!
