It's fun, although at first I had a little trouble figuring it out. I know there's a tutorial and buttons on the screen, but I had to stare at the screen for a while to understand what was going on.I guess it’s also because you don’t have any weapons at first, and the in-game shop menu doesn’t pause the game either.I also don’t think it helps that the enemies block your path...
Still, the music and graphics are great :)
