Yeah, I beat 4 robot masters and have decided to quit this game. It's cheap. There was a part in the mining stage where you go down a ladder and there's drills making tunnels. Not clear to go left or right, I go left and it's a dead end. A drill pins me in and kills me. Same room like 2 ladders dowm, I go right and it's an invisible wall. The tunnel clearly goes right but it stops me. A drill pins me in and kills me.
Same stage, another part. Walk down a slope that goes off the bottom of the screen. Spikes are there, kills me. I also want to complain about the bunch of times where the stun knockback throws me off a ledge or comveyer belt straight into spikes. Annoying.
Next stage, I'm on the highway jumping from car to car. A character named Brand shows up and slashes the car out from under me, killing me. Easy to see coming but not that first time, before you know what he's doing. Fighting this boss, he glows purple when he's charged up. Also glows purple when stunned and you need to dash into him. Not confusing at all, nope.
I went into this game optimistic and enjoyed it the fist night, as reflected in my post above. Since then the game is cheap and frustrated me to quitting without beating it. Fuck this game, I regret so much backing the kickstarter. I will never back a crowdfunding video game ever again, will support post launch instead if it looks good or gets good reviews.
