PSNStores have worked out their Top 25 PSN Exclusives, and decided that Gravity Crash comes in an excellent 10th position. With such a recommendation, you should go to the PlayStation Store right now to buy it! Thanks, PSNStores!
Just Add Water are exactly what you want from a development partner; passionate, creative and hard-working. Every time I've collaborated with them I've thoroughly enjoyed it and the end product has been spectacular.
