Tiny post-submission update based on a couple of received comments:

v1.2

• Enabled window resizing (game may not look pixel perfect, however)
• Enabled fullscreen mode (alt+enter)
• Added option button that lets you swap between goal mode (default) and infinite mode (no end) - game display may become glitched >2000000000 points, and points will probably rollover at 2147483647 points. Beware!
• Added button on the victory screen that turns your game into infinite mode and lets you keep playing

That's it :)
