1: i think that you should make some rewards when u hit an special point in the game. Like 10000 feet give you 10k gold or something.
2: It would be cool if the kongpanions could give better rewards because they arent really that good. (but i dont got alll the kongpanions).
3 Like redgoldandgreen said we need an end. now when i have played a while and it dont got an end i get very disappointed (or its only me) because it just feel that i need an end (then u can add free mode).
4: when u get more expensive upgrades u will need better stuff.
5: Please make an cookie baloon!
6: The achivments should give u some kind of reward. (maybe gold, an kongpanion or an uppgrade).
Well it was very funny but make it better like this.
