Hmm...

don´t know what to say.

You put some of your maps into one episode: Cafe, Wonderful Summer Time (why this one - I didn´t like it!

) and two other maps, Car Wash and one DM map plus intros to each of them, expect for that DM map. Once again, you added some kind of storytelling, but it feels outdated, because it´s once again telling about Duke´s adventures and that´s it. It´s OK, but you should try to think more twisted and interesting storyline and maps... that´s another thing.
So, Sanek´s compilation includes stuff from Duke Caribbean - not bad idea. It´s illegal yes, but it fits to the mod when others won´t. It´s alright that Duke goes off his job whatever it is, fucking women or anything like that, but theme isn´t enough well constructed, thanks to the levels. May sound negative, but that´s how it partially turned out for me.
First level was car wash place in the middle of desert. Scenery was very empty, more effort could have put into it. Area inside was good, simply detailed and well textured, but lacked in shadows, just as other levels, too. Level had some nice puzzles with shrinker and engines, but it didn´t offer anything else as interesting or even more interesting. Outgoing map, after all. The second map was called Wonderful Summer Time. I think I don´t need to explain it any further, because it is absolutely the same old, already released and reviewed map. I didn´t find any modifications at all, if you don´t count Duke Caribbean stuff, such as enemies into it. The third map is Cafe (already released here), now turned into SP map instead of DM, filled with enemies and there we go. Probably the best map of this pack. You fight against the Battlelord in the end that felt a disappointment - I was hoping for a fresh new ending and more length; I wasn´t expecting to see Battlelord as the boss or even any boss, just nuke button after some kind of interesting battle could have been nice, but no, boss battle felt just lame and dull. Now episode felt cheap, because of lack of effort.
Oh, and DM map - sadly it had same theme as Wonderful Summer Time and same detail level outside - very poor and undetailed, uninteresting map.

Overall, it was pretty decent compilation with good gameplay. No gameplay flaws that would have ruined it.

Enjoyment. After all, "On Vacation" didn´t offer anything special and vacation theme just didn´t live up to it´s full potential. Short levels, partially uninteresting theme and poor ending isn´t what great episodes are made of. Gameplay was good for the most part, but it suffered from imbalanced ammo and health ratio. And as MRCK said, "A fun release

"
My suggestion(s): put more effort like time into your maps and remember to beta test them often with help of other dukers as well. That way you can improve your skills, if you really wish to. I hope you understand and want to progress forward. Good luck!
