Could not find the space core :( Where is the old man :( ???. Super nice game and everything was done very well. The music slaps. The artist deserves a reward. Controls are smooth. UI is easy on the eyes. Overall great game.
Suggestions :
-Populate the world with a variety of life (plants, trees, more animals, different floors)
-Add a map
-Add screen shake if something significant happens.
Hope this helps :)
Just some clipping that also popped up while I was playing.
