Unironically the game I spent the most time playing so far haha.
I had a lot of fun with this, it's very smooth and well-designed. I particularly like the difference in pacing of the project tab vs the applications - though I think the projects could be more useful somehow, maybe they could count towards unlocking their own tree of upgrades? I also liked a lot that most of the game could just be played with the space bar (for any incremental game it's good to reduce the amount of moving around or interaction complexity) but I kept having this thing happen where I would auto-purchase an upgrade when I was saving up for another. I'm not sure if this is by design to preload which upgrade you want, but it backfired on me a few times. Also would say the applications come too slowly early on but I understand that's a difficult thing to balance when it's the core resource.
Overall really well done : )
