Gameplay - Simple, easy to understand controls with a simple goal. However the jetpack in my opinion should be able to lift you up even if you havent jumped / are in mid air.
Graphics - Really nice graphics, my own issue with them is that when you compare certain elements like the trees and the gun, the pixels are different sizes, so it looks odd in my opinion. However I love the graphics despite that one thing. Well done!
Audio - Nice SFX, could be even better if there was background music.
Theme - I feel like since the game is set in space, gravity should have less of an effect than it does, however maybe the planet occupies a similar amount of space to Earth in size. Well done for making me think of space in two ways there!
Devlog - A lot of detail, but after Thursday from what I read you probably had time do a lot more so it couldve helped the devlog to go into more detail about what happened after then for each day. For example what mechanics were added, bugs, decisions etc. However the explanation for the reason why this game was made is really detailed. Well done!
