That's a surprising games. I enjoyed fiddling with its physics, but I'm still not sure if I discovered everything. I helped the drowning guy (that I'm tempted to call "Quote" ^^), but he ended up leaving somewhere without me. I've been able to use Exit A, but not exit B or C. Maybe the robot could help for one of them, but everytime he just go away out of water where I can't reach it. A lot of coins and places also become quickly unreachable after garbages are piling up.
But it's a very interesting world to explore. I really ike the concept of a level evolving with time (independantly of the player actions or presence), and a lot of "events" based purely on physics. Plus the grabbing mechanics, while capricious, is fun to learn and master. Overall it was really pleasant to wander several time in this world and experimenting with some of its puzzles! :)
