Okay just done this one. I think I'll stick to kindergarten for this series ... I'm enjoying it :0.
They certainly do enjoy their puzzles in this series. And their rising platforms :). If you get to look at the floor underneath the columns that we have to drop here, you see that invincible/teleport pattern - nice that they made it a floor texture.
I'm not a fan of the narrow passageway mazes that seem to be commonplace in a lot of these levels ... especially with the 'boomers' around it's a pain. Thankfully they do seem to be getting nicer with PBs/rechargers as you say, but I'll have to see how far that trend continues.
I've only been reading your posts after finishing the levels, so I didn't realise you were waiting for me until just a few minutes ago. I'll try to do a couple more tomorrow - am somewhere in the middle of the next as it is.
