Hey, first of all thank you for your comment, I really appreciate it.
I tried to make and include every element (different cameras, coins etc., 1 unaccomplished scene was going down) to learn game development fast, that's one of the reasons that game sucks :) But I have to say reason for floaty controls is gravity being very low in space/other planet and coins are intentional because I thought players not being able to collect coins and drop them down was funny.
It's generally so interesting how a game get a response from any player though. I see that a game must communicate well considering it has little area but too many essentials to communicate.
