Sorry for the laggy product, we have got some technical issues with most/all of the browsers, the reason seems to be the HTML5 Code in a java container .
To fix this issue we will rerelease the game soon, but this time we will use the unity engine.
We will simultaneously fix as many bugs as possible and balance the game better.
Glad you like it!!
Yes, we have considered it! =D and plan to add bossfights in some kind soonish
We'll be updating it regulary - so check back for coming updates ;D
