Idea is very interesting and game was fun, however mathematics of this game is not good.
1) Features are imbalanced
2) Startups are not hopeless, as long as you make code small and rely on constant income from users. (You even can be profitable longer than you can be annoyed), therefore stratup can be good.
3) Not sure why increasing code size makes proportional growth in expences but does not make application better
4) Impressed by how much money you can do, without being able to withdraw them
Total rating 4/5 (because game was fun)
