Hi!
Thanks for your kind words and feedback :)
Could you post a screen of the screen size issue? Is it happening with the downloadable version or the web version? And what is your screen resolution?
Our art team wanted to work on a character and some animation for the Jam so it pushed us to find an interesting way to add it to the game but it's not providing enough feedback right now to justify such a big presence on the screen. We've already some ideas to test to change that and improve the experience and, we hope, address the issues you're mentioning :)
Cheers! :)
