Loved it! I think the things that are already here are really solid and fun, here are some minor feedback points.
- It takes a long time to get to 50 population, so when I lost very close at 48 pop it felt a bit bad.
- It's easy for the gold to run out while I'm focussed on placement of tiles. Maybe different sounds depending on how close you are to losing might help (for instance, almost no gold left, or almost no space left)
- Some seemingly minor choices can have a big impact on your card availability, which can be a pitfall but for me was a fun balance to figure out. For instance, placing lumber camp next to 3 trees all the time might overwhelm your deck with houses!
These are just my takeaways. Overall my experience was really good and I enjoyed the game a lot. Good luck with further development of the full version, keep it up!
PS: I see on Steam that you have controller support planned. Playing this with controller on the couch would make for a perfect relaxing afternoon ^^
