For a free game, and for that it can be easily played in the browser, the graphics are really good. I'm still in a time when even "right" Games like 1602 did not look so good - and you had to first buy for 90 DM and then install yet.
It is primarily as a nice pastime way to work or during the day recommended and entertaining.
Unlike other games you can at any rate also free to play through the game and take advantage of the features, and it's not as "Pay2Win" moderately like other Free2Play Games. The long-term motivation I would classify as high, me captivates the game as long been said, and even if I did not / less played even a week (for example on vacation), which is no problem, I have repeatedly Motivation get to continue playing.
For this free game, there are smooth 5 points!
