I started off playing and thought I wouldn't like the game after dying straight away on the explosive rapids. I quickly realised I got slightly addicted, and had many turns on it :D
The ship control mechanic is amazing and I'd love to see what other sorts of levels you add in.
This could work really well as a mobile game, with many mini-levels to progress through.
The only thing that kept getting me killed was when you click somewhere on the wheel, it automatically turns to that point, rather than doing nothing and only turning hwen you spin the wheel. You need to click at the top of the wheel, then turn if you want precise movement.
Not a deal breaker in any way, just a recomendation :D
