Hey Melerski and thank you very much for your comment and feedback!
The proportions of the skeletoonians are very important, as we have a very strong focus on satisfying game feel. Nothing is worse than a fighting game where you have a hard time seeing what is going on, as it makes it difficult to read the opponents movements. The last thing we want is to frustrate the player. I will take your feedback and send it to the design team right away! :)
As for your last questions. Maybe, maybe and maybe. Right now we are focusing all our energy into the core game-play and then we will start adding flavor. :)
If you want to be around for that, be sure to sign up for our Alpha. We could use more feedback like yours. --> http://heroblocks.com/hero-signup/
Have a great day, and thank you again.
