Nice little game. As it has been mentioned, it would have been much MUCH better if the board was tilting, and more than making the game look better, it would have also helped with gameplay understanding.
Explosions look nice, but they are a bit too omnipresent, making them fun at first, and then they're just a part of the environment, which is definitely not their point. I also think the map lacks some mechanics, like more holes, more random bumpers, because here you just have to keep going again and again until there are no more obstacle, and you're done, making it not really challenging. The fact that the bombs respawn also makes it a bit easy, though it would have been too punishing if they did not, since, once again, they explode too easily :p
Hope this feedback will be of any help !
