I spent a few minutes playing your game, or rather mini games and I did like it as a whole, but I think you need to add skip buttons in various places ^{[the animations are a bit slow or long and IMO, become somewhat boring]}. In the game that requires driving the price to new heights, the sudden drops from hitting the sell blocks are way too fast and lastly, the only way to make it more fun is probably to reward your loyal users in some way.
