Very cool way of displaying history and man the puzzle games are doing so good in this jam, they have been some of my favorites, the complexity of this one is pretty steep, but I enjoy a good challenge, I think as others mentioned, easier levels at the beginning could lead the player to figure things out faster, but overall the design, and style is really cool! 

Overall I am still confused on how to play this game. Spent an lot of time trying to figure out what and how to do in this game. Probably to much information being presented at one time in one go.

But overall I liked the graphics.

I really liked this, solid ratings all round. My biggest gameplay criticism is that failing should be "restart the level" not "restart the game" in a game of this length. The most major bug was that all the captions for the event seemed to show the one for the prehistoric land bridge, which was a pity.

On the history side, some of the presentation of things could have been made a bit fuzzier, making it clearer in earlier periods that the events were "circa" and indeed were in many cases really processes, rather than the slightly old-school "this happened in this year" way of presenting things.. I really liked the red herring events and I particularly liked the half-plausible sounding ones (like "Romans invading Ireland"), but wasn't sure they did much game-wise (unless there was some penalty for drag-and-dropping them that I didn't find).

Anyway, generally really liked it, good job!
