I loved the overclocked NES Visual ! Indeed, so much particles at once, it would have struggle to render this. I quite did not understood the mechanics though, I finished the demo but I played without understanding what I was doing. What were all the different monsters ? And why when having 100 mini crystal does not transform into the one big one ? And the void ennemies were actually helping me gaining the crystals ? Anyway, I craved a bit of explanation, but aside that, the game is beautiful and funny and has a lot of potential for extension. Great job !
