I'm disappointed in this game, Nano war was really good and this sequel didn't do much for it. Having to repeat the same level over and over so that you can get upgrade points is frustrating, and I don't find myself as drawn into the game as I did with the original.
Decent game, my main problem was with the course design. It didn't look like a track, and it felt more like I was following a guide rail, like the bike was being pulled along in some parts.
Disliked the firing system, taken too much damage from having to throw my ship in the way of oncoming enemies to shoot them. Very repetitive, nothing which makes me want to play on, upgrades, in-game achievements, bosses, weapons? Minimalist gameplay styles are boring if you don't have the right formula. For example, Ragdoll avalanche 2, I used to play for ages improving my score. I couldn't bother playing this after only a few.
I like the game, but it isn't original, it's more of a mix between Crush the castle and demolition city. The variety of ammo types are fun to play with, but I would have liked to buy them with the loot instead.
