I still like Raiden better
Not the best top down space shooter on NG. This game needs to be a bit harder, which means less money and health. A more dramatic storyline would be nice as well. Lastly, I couldn't tell one level from the other. I played the first three levels, and even the bosses looked the same.
Still, I did like how the shop worked, even if I could easily afford to buy every item in it. All in all, this is a neat concept, but not really something I could get into until there was more variety and a higher difficulty.
