Thank you very much! :D
A playable demo is planned, I saw many other android games here doing this and its a great way to test game before downloading it, but it will take some time, like you already saw ingame its still pretty early in developement but playable :).
The Browser version initially got uploaded so users can play it without problems and without downloading stuff. Especially friends who have an Iphone... This will be a problem, if I can't set a price for the web version
