Fullscreen on laptop's external monitor uses wrong resolution
Playing on my laptop, with built-in screen 1366x768, and an external monitor 1280x1024. If I drag the window to the external screen and hit [tab], it does correctly go fullscreen on the external monitor, but it looks like it's rendering to a surface which is the size of the laptop built-in screen's resolution. So, in my case, that's wider than my external monitor, so the right part of the screen is cut off. I can only see "Time" and "Gol" where it should say "Time: 99" and "Gold: 0". Vertically, the game doesn't take up the full height of the screen, and is positioned up against the top edge of the monitor, leaving a big black gap at the bottom of about 20% of the monitor height.
Playing on my laptop's built-in screen is perfect, either windowed or fullscreen.

This isn't a bug that bothers me (I can play happily on either screen), and I understand you aren't supporting Linux. Just reporting in case it turns out to be useful (maybe it happens on other platforms too?)
Am LOVING the game though. Saw it mentioned on rockpapershotgun. I'll be sure to post something about it on facebook, etc. If you ever put out a paid version, consider me signed up.
