I think the game would be more difficult if, instead of being able to upgrade the three catagories once each, they all had 3 lvl ups that increased the power.
This would make it harder to beat the opponent on each level and therefore making the game as a whole more difficult. Different difficulty settings could give this game some replay value, maybe you could incorporate my previous suggestion of level ups into this e.g: on easy mode the enemy could start with less clouds, less upgraded clouds and it takes the enemy longer to upgrade. On hard mode the opponent could start with more clouds, more upgraded clouds and they only have to get one upgrade to reach max in the selected area additionally there could be more different opponents in the levels. Good luck with any future endevours and please, please, please add a level pack or even a number 2. Thanks. =3
