Thank you so much for your kind words and such a detailed review!
(1) Definitely, the first thing I will change, I’ve received a lot of feedback about the intro.
(2) “Proximity alert” is a really nice idea, I will consider it to improve this aspect of the game, for sure I need to find a way to tweak it somehow.
(3) Really interesting point of view and thoughts about the way the player is rocketed up and the constant speed, I’ll certainly give it some thought having in mind your input. I wish I’d had more time to make a better difficulty progression between levels, unfortunately I ran out of time and some of them might look a bit inconsistent, in addition some floating things probably too dangerous.
(4) Oxygen and mini-stations concept sound great. I’m thinking about introducing more variables to the game, I’m not sure yet though, I’ll probably polish everything that seems a bit off first and then I’ll introduce new features.
Again, thanks a lot for all your input, it is surely helpful, I really appreciate it!
