Thank you for your comment! We really appreciate that kind of comments.
In a couple of days or so we will release the Alpha 4.1 with some bug fixes and lowering the supplies cost and room furniture (the needed: toilet, shower and bed). After the Alpha 4 release we realised that it was complicated to expand the hotel, and that is boring!
To get prestige you need guests leaving happy (by "happy" I mean that leaving at the time they should: even if they are angry, if they pay the full room price it will increase a bit the prestige) or to build decorative objects (everything that hasn't got an utility are decorative objects, for example: paperbin and bin, lights, pictures, sofas... The "Hotel Certificate" object is the expensive but is the object that more prestige adds).
About the speed control panel, yes, that's a planned feature! But thank you for the idea!
Anything more, just tell us!
