thanks for the feedback and updates. I have increased the intensity of the lights. Also, I have added several teleport doors to help going back to the surface. I have increased jet pack duration. The lag should also be fixed in the latest version. Please let me know if this is not the case.
Going up with the new fuel amount was pretty good + the teleportation was very nice. Now i did experience a bit of lag but it wasn't as much as last time (this is edited because i accidentally sent it before i ended writing). Now i ran into another problem, when you fall with high speeds you get stuck to the ground like on the image anexated with this message. So here are my new suggestions:
1) Add a button to return to the top if you are stuck, the rescue fee is all the ores you have on you in that instant(in short a way to avoid being softlocked) .
2) Make the jetpack a bit faster as its pretty slow going up.
3) (if possible) a save system as to not lose the run if the game is restarted.
For now that's about it, as the image above shows this run seems to be over, ill atempt it again at another time. good luck with the game! bye.
