Hello Samapatti! Thank you very much for this feedback, I don't know if we're going to make a Linux version yet, but it's good to know
Second the request for Linux compatibility. The Godot engine might me a good alternative to Unity; cross-porting is supposed to be much easier
It seems, that Unity3D Editor (not sure if it allows also to export for Linux-Platform though) is now officially supported for Linux, too - as it was reported at the Unity3D Blog at the End of May.
I'd be curious, whether or not Unity itself - regardless on which platform you create - now supports also to easily port it to Linux-native Systems, as "abnormalplayground" 's suggested "Godot" Development Platform does.
Oh, I just found this interesting Thread in the Game Development Forums, that shows, that it should be fairly easy to just install Linux Platform Support on Unity. What do you think/say? - Sounds pretty easy to me, if that works fine/properly and doesn't need any special "adjustments", that cost loads and loads of more working hours, of course.
