Not sure if anyone is interested in metroidvanias anymore, but it does have extremely well done pixel art as a bonus. Anyway, I had helped Kickstart this game, so I was given alpha-testing access. But I believe you can also be a "slacker-backer" and dig in now and gain alpha access as well. I've already chugged in 3 hours, visited 3 areas, and beat 2 bosses. So it's a pretty fleshed out alpha. Hell I'm not positive they haven't tried to put in the whole game in glitchy alpha access (I only came across a couple glitches, notable, but nothing I'd write home about)

If anyone is interested, as a backer and a fan, I think I'd like to see the game get more love. Also the world needs more metroidvanias. And anyone whose a fan of that style is probably on the look-out for them anyway. So here you go. Do with it what you will :3
