I was playing The Room on Bluestacks, and the game requires features of a real android device such as multitouch, tilt, shake and swipe. Although the first level was quite simple, and required only swiping, I finished it quickly. But the second chapter has many functions like tilt and multitouch. I don't know what it has in the third chapter as this game has 5 chapters in all, and I was stuck at the chapter 2 multitouch part where I have to swipe to switches at the same time. So is there a way to complete it?
I actually opened a thread on their forum about this. While there are 3rd party options, as mentioned by lucky (I personally couldn't be bothered messing around trying to get these to work), there is currently no support within Bluestacks itself.
As mentioned in a post from the xda-developers forum,
If you want experience multitouch on bluestack but your windows not have multitouch screen install Droidmote Client on your phone (free), install Droidmote Server for windows on your windows. For example, in google maps you can zoom in out rotate with two finger etc.
