I like the bomb and shoot combo is something new and very skill based. I think the mini games are a good idea to shake up the game play, but only happen one time in the demo for me. The art is also decent.
At the beginning i thought you only had 3 bombs and couldn't reload. So i was way too careful with them. I think the day transition looks cool but takes too long. The ricochet seem way too strong instead of shooting at the fish you can just shoot against the walls at a low angle and the bullets basicly stay forever killing everything without any effort.
Really cool game wish you BIG money.
