Thank you for sharing your game! I enjoyed playing trough it.
I noticed the loop levels for skills have very little impact. They quickly reach level 15 but hardly level after level 20, I reached the end with 26 Tech and didn't feel its impact.
The tasks with permanent progress are the real meat of the game, choosing your route to reach supplies and objectives with the least wasted time possible.
I suggest removing experience and instead adding tasks with temporary or permanent skill boosts. You could get a 20% exploration boost from Marie's diary or get either a Destruction or Tech temporary bonus for repairing power tools or hacker tools. This would put the emphasis on routing and achieving instead of misleading veterans into thinking you can grind loop levels.
