Without 'landmarks' exploring to find resources felt very hit and miss, kinda like harsh RNG. If finding resources were based on RNG then maybe tuning the system so that it isn't purely random could help.

I had a lot of fun with the blasting off and landing physics. The 2D Art in the 3D world helped the resources and landmark/ship stand out.
Trying to balance the O2 meter with the jetpack fuel meter was really engaging until I found out that I could still use the jetpack without worrying about fuel; this may have been unintentional?

Really interesting concept, would have liked to have the ability to turn the character instead of strafing, and have the camera be positioned better to see what's around easier. Having more items around like rocks and possibly landmarks that were recognizable would help out exploration as well.
