Suggestions needed on $.049 (U.S.) games to use for steamgift giveaways

Ghost Master
Edit:
Defy Gravity is also really fun.

Bit Blaster XL
Timberman
Out there Somewhere
The Deed
Ubermosh
RUSH
Roll'd
Frankenstein: Master of Death

The 12 Labours of Hercules games are fun. The last one hasn't been in a bundle yet, so probably not too many people have it.

English Country Tune might be okay for puzzle fans, too.
Rolling Sun (is kind of a boring rolling marble game if you like those, but it really seems to run hot on my 660 Ti (up fan to.. 65%%%%) and has some performance problems)
Dreaming Sarah I thought was entertaining, if you want to go up to $0.59

Thanks everyone. Some good info for me here.
