Hi there, oh no sorry about the bugs with the visitors :-( That sounds very annoying but thank you for letting us know. Also sorry we don't have much in the way of tutorials. Adding tutorialisation can take up a lot of time and we decided to put that time towards new features for this prototype but I know it's not a great solution to just expect people to figure it all out on their own.
For our next demo release (which will also be on Steam) and definitely for the full game, we will have a proper introduction and tutorials. We will also try to include other options for controls and we are adding controller support if that suits you better.
I'm so happy you enjoyed it despite the issues you had!! If we can turn you into a gamer then that makes me very happy XD Thanks so much for the support.
