Good Game, buy it, it's fun!
This game really rocks! Though it is retro-style.
In order to get widescreen support you need to look at this page:

i play it in native resolutions on my mbp and my imac.
vp should make the widescreensupport and high-res support directly in the game-menu, this would be much easier. the loading-times are a bit too long, but as I said before, the game rocks! excellent atmosphere really good musik and sound and detailed 2d graphics. the animations could be a bit better, but they are absolute OK.
I have some lines in the game which are a small bug, but i think they will fix this and make the scrolling a bit smoother.
good game, buy it.
