They do matter! Not in the demo, but in the full game. Each board will need to be maxed out to prestige, and prestige will allow for buying global upgrades. Definitely not worth investing in the demo though! XD
Really good to know. The game plays really awesome and feels fast enough for an idle game that I was actually more engaged than other idle games I've played. That's a good thing as I felt like the dopamine was hitting often enough that I didn't just minimize it and walk away for hours and hours. I'll certainly wishlist this. Best of luck and great job.
