Quick review: I read several times (and from the devs themselves) that the game was a bit too talkative but I didn't think so. Only the introduction scene talks quite a lot (so be warned! But I liked it, nice humor), and after that you're more busy trying to find the correct item to use at the right place, so text is not an issue anymore imo.
I found the game was getting slightly difficult at some point (particularly with a pixel hunt, and I'm not a big fan of this). That being said the whole adventure was incredible, I really liked the art (Esmeralda's drawing are always great in all her games) and the story/gameplay are perfect for such a short point and click. I'm always surprised and impressed by the way the creators end up using so few environments and yet telling so much, and creating so many interactions in such a small world.
A Sirius Incident was quite lenghty for a short game (1 hour?) and was a perfect balance between fun and curiosity! The version I played had a few issues and lacked some music during gameplay, but devs said it could be fixed someday. Overall, great point and click adventure!
