Great update!
Grid design is huge!
After testing with the grid design it is a huge improvement, making that intense early game flow much better.
That preview level, I'm not sure if it is meant to be that difficult but it was indeed fun! A level where your base is dead center of the map, a true last stand, great idea.
On that note: I think it would also be incredibly fun to have a mode like this, but where you are given an ample amount of time, even something like 5 or more minutes, to prepare yourself for a massive enemy attack, like a true boss level or something, although I'm sure you have some ideas about boss levels for the future.
One thing I'd love to see in a future update, is hotkeys or hotkeys within menus. I.E. "F to build Factory" or "E to upgrade" from within the building's menu. I think it would both serve to help more easily meet the fast pace of the early game, as well as pay homage to staple RTS games of the past.
Love that you specifically implemented some of the things I outlined in the previous comment, in this new update. I thank you for that, it feels nice to be part of your journey.
The new cards, the increased size of boosters packs; the touch of color on Giants! All welcomed additions. It was very fun to revisit this game and once again I look forward to seeing what future updates bring. Wish the best of luck 🙏
