+1!! Very good levelpack. The music tracks are very good and fit very well. However, I don't consider myself to be 100% objective wrt music, due to my being biased towards Christian's tracks and the way he views the turri "ambient sound texturing" in general.
Previous levelpacks with the "Lukasz" signature had many levels and this feeling of an "epic quest" so that the player would feel "rewarded" after completing the whole pack - like the outcome of an ancient tragedy. Also, the "Lukasz" signature was synonym to consistent, well-thought, challenging and very beautiful levels that an experienced player would, at first sight, appreciate and realize the amount of work put on them by the team. Professional in terms of quality, fan-made in terms of fun! What would anyone ask for more?
With this levelpack, I think Lukasz' greatest feat is that he achieved the same experience for the player in fewer levels than his previous releases. This may seem easy for a battle-scarred veteran like him, but it's not!! When I finished it I was under the impression that I was playing it for days, although it took me a couple of days. All the elements were there: progressive difficulty, power-ups well-spread, maximum play-ability, right game pace, addictive gameplay without boring moments. The climax (last big level - aliens) was chaotic!
Again, congrats and BIG THX for yet another quality release Lukasz and co!!!
