Just played a good chunk of the levelpack (all the way up to level 19, which was just a tad too long to finish) and I must say I really enjoyed them.
There are levels with puzzle elements and levels that focus more on platforming (the latter becoming more prevalent in later levels it seems), but that's just the kind of mix I like to see.
It was also nice to see some level concepts/ideas that are common in most levelpacks (e.g. dropping down and avoiding spikes) as well as some novel level concepts.
Anyway, thanks for the levelpack!
I'm trying to get back into game (development, I mean, not just playing it
) and it's really nice to be able to do so with levels that were new to me.
