Absolutely GORGEOUS game. The art is amazing (definitely top tier), the gameplay is smooth and the weapon of choice is very interesting! Also, the music takes me back to castlevania, obvious inspirations. I can see this becoming a bigger game with a full story, it just invites us to know more about the world and to PLAY more! Interesting way to incorporate the SPACE theme in the gameplay too!
I can feel the game boy vibes from the title, but I think the monsters, characters and maybe even the scenario are way too complex for the game boy. Too bad because I was DYING to test it in the original hardware, it remembers a little Fallen Crown. T-T
