Thanks, error fixed.
I forgot a file in the archive, although the error does only occur at the first start.

For colorblind people here is a simple solution:
Just put an option into the game that displays signs on every block. For example red blocks have a circle on it, yellow blocks a square. Blue blocks a water drop or something like that. Hexic HD for XB360 uses the same technique for colorblind people

Yepp, very nice idea with a comfortable realisation.
Thats the kind of game more 3d gs (hobby) user should create instead of trying to reach the unreachable aim of creating high tech games in concurrence with the top game software developer.
So congratulation - really useful

The concept of the game was definitely interesting. As a game that you could play to kill time, it's pretty neat. However, I don't know if the game would hold up on just the features included for any other type of gaming. As Rackscha stated, you may want to try out Hexic HD, if you've never played it. Adding a feature similar to the Color Bombs could really add a sense of urgency to the gameplay alongside the time limit already in place. Maybe you could also find a way to tie in objectives along with the score, or level progression ( ie. Destroy 5 color bombs to move to next level. Next level contains new mechanic similar to color bombs) if that would help you reach what you want to achieve.

The menu was well done and aesthetically pleasing. It took me a few seconds to realize that the menu rotated left and right, but that may be due to the fact that I was paying more attention to the style of the menu, which was enjoyable.
The overall art direction had a very minimal feel to it, and worked well in my opinion.

I could imagine this game would be released as freeware, as-is. If you were to add more features, such as the Hexic suggestions or other mechanics, this game could EASILY become a small retail release in the puzzle genre.
