Strange... we've had a few people test on multiple machines and none of them had any issues. If you're at all interested, the game logs are at "%appdata%\LocalLow\Road Turtle Games\Scanline Survivors\Player.log". You can send them to support@roadturtlegames.com and we can take a look.
I would also be interested to know about the stance on balance changes. I'm definitely feeling the urge to try tweaking a few variables to improve our gameplay just a bit!
