Thanks for playing!
About the controls, yeah seems like quite some people had problems with trampolines on the edge of the screen, I'll try and fix it after rating period ends.
I disagree with you on the angle/length of trampoline not mattering though. By using shorter well aimed trampolines you can go for certain stuff in the level, and as you said, shorter trampolines are riskier. So I think that makes it so that skill does matter somewhat, some people were able to reach the moon in like a quarter of the launches. (But luck is a factor as well, give you that)
I'll try and fix some of the balancing of the shop upgrades so that you don't necessarily need all of them.
Thanks for all the feedback, appreciate the review!
