This is the first game in the Elsa-Verse series by Tora Productions (Tlaero & Mortze), and, while it is only my second-favorite game in that series, DWE is still one of my favorite adult games of all time. This game, and the others in this series are unique for me in that I would still play them (and look forward to new installments) it they had little or no adult content. The art is great, and the writing is absolutely top notch. While the sex scenes are very hot and well-drawn (LOVE Mortze's art), it is the writing that makes me keep coming back to these games. The second game in this series, Redemption for Jessica, is, to this date, the only adult game that has ever brought me to tears.
Making it through the game itself to a good ending can be a bit of a challenge, because the "best" choice in most situations isn't always what you think it is (at least their games are that way for me), but I find it well worth my time to explore the different routes to find the different endings. If you are really stuck on the game, you can find a good walkthrough for it with a quick google search.
If you like this game, I highly encourage you to check out their other stuff. T&M are among the very best developers in the genre today.
