As a player and as a game designer, I usually hate driving games; never really that fun to play, and a headache to design.
And then there comes Modus Interactive, with a mind-bottling (yes), fully-realized vision-of-a-game. The fact that this much could be accomplished over the month-long duration of the game jam is stunning, even somewhat intimidating.

Mixing the best elements of Twisted Metal, Death Race 2000 and Tony Hawk Pro Skater (yes!), Groaning Steel has this hypnotic gameflow inviting players for a never-ending cycle of 'just one more try'. You'll want that score. You'll want those unlocks. 

Presentation is also top notch. This is miles beyond what could reasonably be expected of the scope of a game jam, and is a game I intend to play again and again for quite some time.

Highly recommended.
