Hey, I noticed on my channel that you asked me to check out your game, so I gave it a try. :)
As others have mentioned it would be improved a lot by more UI and tutorial elements explaining what to do. I think your idea to add a minigame at each station sounds fun, though you'll probably have to slow down the reactor timer in that case.
Congratulations on making your very first jam entry! I can tell from your comments that you've learned a lot from the experience, so I'm excited to see what you do next.
