So the best investment is Time Warp instead of Energy? I've been saving some diamonds for this reason, currently I have 100 and as soon as I finish with Geeky I would be able to buy 20 Energy wich seems tempting since it will give me more room for upgrading girls while I level them up but the Time Warp seems like a very good choice too considering it increases the rate at wich you get skills and Im already waiting for a day for lvl 21-22 and I don't see how I could get to 32 at this rate unless I wait for months.

Also I've been trying to get all the files for the wiki (already have positions/animations done for the first 4 girls) and I started seeing some costumes I don't know how to get like the halloween ones people are talking about and I also saw some Cherrys and Lolas with winter jackets, how do you get those?
