Download SkyTracks (Windows)

From the old developer website:

SkyTracks is a racing puzzle game. Complete each level, and unlock stages in a puzzle campaign. Your aim is to destroy all the spheres in each level, by knocking them off the track, crushing them, or from missile powerups. You are rewarded for each level with bronze, silver, or gold awards.

Use physics to launch your vehicle in the air and scramble over obstacles and traps, such as pendulums, hammers, and crushers. Try to get the best time to win gold medals for each level. Find and use different powerups to get a super jump, super speed, and missile capabilities! Watch out for different track sections such as sticky, bouncy and thrust areas.

As well as the puzzle campaign, play the standard race mode. With AI, or face up with your friends in MultiPlayer. Play with 8 of your friends in a standard race, or last-man-standing arena.

SkyTracks has a free demo version that you can try out for yourself!

To install the Czech translation, unpack the ZIP extra and put locale_czech.pak it into the game directory (normally C:\program files\SkyTracks).

There is no way to select the locale yet from the launcher. To set the locale to czech, open up settings.xml in notepad (you must have run the game at least once for this file to appear), you will see the "g_ActiveLocale" entry. Change the value from "english" to "cesky".
