There is a new version of the demo out. Here are the fixes for version 1.3:
- Fixed crash when a whirlpool sucks in bits that fly off damaged enemies.
- Fixed bubbles turning into squares.
- Fixed instructions so they work on the demo.
- Modified bosses to explode with more stars.
- Added the missing characters from the Turkish alphabet.
The next update (1.4) will include a bunch of performance enhancements. The backgrounds will change to require less processing power so the game should run better when the screen is full of bullets.
