Thanks for the feedback Kuzmaka - from what you're saying, it sounds like you weren't aware that Up & Down on the right thumbstick controls the vertical movement, so I imagine not using that would give you quite a different experience. I did want to put in a controls overview at the start but unfortunately I ran out of time for that, so I had to resort to putting that on the game page (which is easily missed) - I'll definitely put it in for version 2 though!
Maybe give it another go and use up/down on the right thumbstick to control your movement and see how it feels then?
As for the vertical movement not necessary for gameplay, I see how you would think that - however it inherently is... As it's a zero gravity environment (which is kinda necessary for the plot ) any important items can spin off anywhere, so it's necessary to still be able to grab them no matter where they go - hence the movement style. However, putting in distance grab as a different solution would then unfortunately make the other gameplay elements too easy. They have to be time consuming enough so they are a challenge against the time critical threat, such as filling the O2 tanks. Hope you see what I mean there? I'll have a think about alternatives though...
Glad you enjoyed it regardless, and thanks for the review!
