I have a lot of games, and the only two I regret to have pay for, are : Zen Bound and Rolando. It means I hav no egrets or the others
Soul Trapper. Bought at full price, which was $7.99, in the wee hours of the morning before a trip. Checked the app store a while later out of curiosity and saw that the priced dropped for a temporary sale all the way down to $1.99. Still didn't regret paying that full price. It really is one of the best friggin' iPhone/touch games I've played, and that's saying quite a bit considering it's an audio adventure game (meaning no graphics - other than still pictures - everything is driven by sound).
