Okay, so I'm thinking the breakdown will be:
- Underhaul: $2
- Pixi Poxi: $3
- Stacky Stacky: $2
- Ice Block Puzzle: 74 cents
- Each of the other games which are normally free: 75 cents
That's $2 off of every game that normally costs money, and a decent amount for those who don't normally charge without chopping too much into the profits of those who charge. If there are any issues with this, let me know - I'm no expert, I'm just winging it, and I don't want to be unfair about the pricing of games that you've put time and effort into. This would make the bundle cost $9.99.
