I see you're everywhere leaving feedback, man! Massive respect for the dedication and supporting the community.
The concept for SFDS Plus sounds really cool, especially the incremental loop and adding that mini 'roguelite' feel to the upgrades. It's awesome that you brought this vision to life from your old Python project!
You did a great job managing the time for this jam, but if you have a spare moment between all the comments, I'd love to know what a fellow tycoon/incremental developer thinks about my game as well! Good luck! BTW i see that you have almost 3 days beafore Why haven't you added more stuff?
