I really appreciate that you like the game and that you're letting me know here! Of course I understand that plenty of people do, I've read many positive reviews and heard nice things about it. Now, I know from myself at for example the Clickteam boards, that I tend to focus on negative stuff. I'm right now holding a course in game development for the university and learnt a lot about how beginners percieve Multimedia Fusion 2, and what could be improved to make it more beginner friendly. Of course I point out this big list of changes I suggest, which I suppose can make it look like I only think negatively of the program. However, in six hours the people taking the course knew enough to design a simple game, which means that MMF2 worked incredibly well and there were tons of awesome things I could have said about it.
So even I work that way, I tend to focus more on what went wrong than what went right, so of course it's going to be common on a forum like this that you see complaints. With Saira, it's not unexpected really. It's a difficult game that requires the players to both appreciate platforming (even timed sections) and tricky puzzle solving. There were also many expectations based on my previous games, and Saira didn't move like you do in e.g. a Knytt game. The same thing happened in Knytt though, a lot of people who really liked WaDF was put off by how easy it is and how it didn't have the same kind of challenges. However, I tend to get criticism on the forum while I get the more positive feedback through my website's "contact me" form, I'm not exactly sure how that works.
Directly after the release, I was worn out and only saw the negative opinions, despite that even a lot of people back then said they really liked Saira (and I've heard a lot more positive stuff since then). The sales have been satisfying (in particular after the game got up on Steam), so now I know that things went really well! It makes me happy that you and many other people enjoyed the game, as I really put my heart into making it (and I'm sure Yann did too with his music skills), so thanks for letting me know! It means a lot!
