Micromakers: Cookie Factory made me rather hungry, although it lacked that "just one more go" mentality, that would have really benefited it.
A fairly original idea: players control a cookie cutter within a factory. Cookies steadily make their way towards the cookie cutter, requiring the player to line up the two shapes so that the cookie comes through completed. This process requires rotating a ring on the outside of the cutter, in order to move it around. It's pretty simple to do, although I did find my fingers getting in the way of the action at times. Shapes vary from simple hearts to increasingly intricate flowers or even crabs. Variety still somehow feels a little limited, though. Mostly because each level is a repetition of the same shape, throughout. It's not so much that it's easy to line up the shapes (Micromakers: Cookie Factory requires great accuracy so it's rarely simple), but it's not interesting enough to persevere.
This idea continues on for many levels, with over 40 levels of the campaign to tackle. After a time, two new game modes unlock: streak and marathon, but the core idea remains the same and, again, lacks excitement. Micromakers: Cookie Factory struggles to evolve past the opening few minutes, never adding anything of sufficient value to really draw one in.
Micromakers: Cookie Factory might be an interesting idea but it lacks a certain sense of excitement to really thrill. Given it's such a speed focused game, online leader boards or some achievements would have gone some way to enticing players to continue. However, Micromakers: Cookie Factory lacks all that giving players few reasons to continue playing after the initial few minutes of intrigue. It still made me hungry, though.
