When I was a kid, I had a simple metric for my toys and my money: for every dollar I spend, will I get an hour (or more) of enjoyment from this? If yes, then it's a good deal. Ollie's has two in-app purchases for Snake and Tranquility Touchdown, and although I've only been playing for an hour, my 12 year old self's adage holds up. The games are a lot of fun, and price is a heck of a deal. I hope more games are added in future releases! (Lights Out and Missile Command are some personal favorites.) Also, here's a Snake tip for reading my review: the screen wraps around. Have fun, and thanks Iconfactory for another great app/
