I am really enjoying Eden; it is like three games in one. First, is the whole, complete all the levels while exploring concept. Second, is the high score and race against the clock old school gaming concept. Third, is the trophy reward system, which is well, a rewarding gaming concept.
I am not very far into the game. First two gardens are complete, and I have earned two trophies for clearing (rather growing) all seeds on said levels. The game is fun and highly addicting. It is really easy to get in a zone, and just keep plugging along. Good stuff and well worth $9.99.
