Hey there, Programmer for GS here. Appreciate the post, loving the feedback and more detail is always good!
For the bugs, we've already fixed the camera zoom and that will update in the 0.2.0 update.
For mobile controls, that's probably our biggest complaint right now is the mobile controls suck. If anyone has suggestions on games that are like GS but better on mobile, I'd love to hear them so I can give it a test and see what they're doing different/better. Or any suggestions ( we know the left stick is a big issue for some)
As for your recommendations, they sound great! We have a pretty good idea on everything that will go into the early scenes like Forest, Beach and Mangrove. But we usually keep suggestions in mind for our later Acts.
3-somes are already a thing, we have the code in place right now actually! but the only art we have is with 2 conductors (you should be able to see that in the previous builds!)
And we'll add more as our artists dish them out. Personally, I'd love for us to get a combination of each type of combo but that might be a bit much for the artists at least in the short term!
A down attack and double jump don't seem like bad ideas but we'll have to discuss those internally.
Appreciate the feedback and support!
