I gave the game only a 15 minutes or so, but I liked every one of them.
The sound is good, it's clear what's happening and the music isn't grating (unlike many of the other games I tried, sadly).
The graphics looks really nice. I had some issues recognizing what's dangerous and what's just a scenery, but some issues like this are probably unavoidable in this low resolution. You most definitely go a lot of bang out of it: the game is really nice to look at, and the screen is busy but not cluttered.
Frankly, I am struggling to find anything negative here :)
