666 gifts sent [Level 2+ GAs ending on Feb 12, 6am UTC] [Hint added]

One day I noticed my gift count approaching a "nice" number so I felt like it's a good excuse to make some gibs!

Since I'm lazy, I asked for suggestions instead of coming up with my own list. I'm not buying everything mentioned in that thread though (poor student and no sale going on), so I picked a few at random.

Anyway, these are the games I'm giving away:

• Zero Escape: Zero Time Dilemma (999 is not out yet so I opted for this :/)
• Devil May Cry® 4 Special Edition (may not be able to activate this in Japan)
• Pony Island
• Devil Daggers
• SEUM: Speedrunners from Hell
• Mortal Kombat X

Since I'm evil, I wanted to torture people with my stupid puzzle. You have to find the entrance yourself though (the giveaway is for Level 2+, no SGTools). You should be able to solve everything on a common desktop browser like Chrome, without downloading anything. Here's a puzzle thread that you may find useful.

Don't want to solve my stupid puzzle? No problem, here's an SGTools-protected train for the unmotivated peeps.

If you want, leave me some suggestions for fun escape games? A few that come to mind: MildEscape, Neutral and Robamimi. They don't seem to be regularly updated anymore though.

Have "FUN", and please don't share hints/answers/links :D
