Overall this game felt very tightly put together. The audio really fit the mood and ambiance; the sfx and music at the end sounded great, but it might have been nice if the other levels had some music too. The controls were extremely responsive (but I did feel a bit motion sick a couple times). My favorite part was dropping the bombs (though I still never figured out if they were timed or if I had to move around to ignite them).
I liked the mini-map but it was difficult to see the little black square sometimes. Also I did get lost on level 3 when I couldn't remember which room the stairs were in and the mini-map didn't show it.
Enjoyable experience for sure.
