Reached the "frozen ending", it was fun! And it taught me to never take a shower in deep space.
It's already a well polished game, probably the most solid i've tried, everything works perfectly and it's interesting to learn the mechanics.
Thank you for your feedback.
And maybe these endings are unnecessary, but if you are curious about the possibilities, you can test all of them... But later when I have a save game function in the game :D
