Nice little game! I meant to try it out for a little while before bed, and here I am at 3AM coming back out of full screen, lol! Haven't managed to get over 84 yet, which is frankly a bit embarrassing. But my scores are still improving, so I'll be back.
I would love to see sound effects added for placing the hexes, something with a bit of pop. Some sounds for the chaining or growth of houses/parks/dock connections would be great too. I think with some good sound effects, and a bit of good/bad feedback from particle effects when placing a tile, the scoring could be made more obvious. I had to read the instructions to understand why windmills were giving me negative points, for example. The scoring is great, makes sense, and feels well balanced once I understood it though!
It's tempting to request music as well. Though with how many times I played already, maybe that would just get irritating and take a while to load for not much gain. It's easy enough to play background music ourselves.
I also second the request for a way back to the menu from in the game. The instructions are there, so right now we have to refresh the page to go read them. It would be great if on the game over screen there was a link to the title again. Alternatively, a quick reference of the scoring values in the game itself through a popup card or something similar could help.
Thanks for a fun evening, and congrats on the jam too! This is awesome!
