Wow! If you love platformers, this one you must buy. First I thought this was just one regular NES-style platformer with traditional gameplay. And it is mostly. Very addictive and amusing gameplay. Music is so good! But it gets better...
4/5 with standard WASD+mouse 5/5 with controller Conclusion: Use controller! That is the way I enjoy it. Maybe it is little easier prehaps but there is still hard time for you if you don't use your weaponry careful enough. Don't worry! It is not boring ammo management simulator. But many situations requires weapon switching. Still, more often than enough, basic boomstick will do. Fun!
