Seems like something's broken. I'm just in the scene with the bird, skunk, and fighter cat and can talk to them but after the last screen of text for each conversation it looks like the text flashes "null" for a frame before disappearing (I'm not seeing any errors in the browser's dev tool console window though). The game isn't progressing, it's just that one scene and if I walk to the distant end then it throws be back to the front. The 3D is pretty off 'cuz the characters' feet don't stay in the same place. This looks like it could be cool, but is way buggy rite nao.
Edit: Ok, it's working now without any major bugs. Ramasama-kun isn't changing colors after the kiss at least for me and looked like he was still flashing null for a frame at the end of the conversation, but the game still seems to count him as kissed because it completes after I talk to him and everyone else so it's not game breaking. And when characters spawn pretty far in the background they sometimes have horizontal movement as I'm starting to approach them that seems off in terms emulating 3D.
As for the game as a whole, it's sort of an art game without real gameplay so it's in the eye of the beholder -- I can respect making a 3D game from a 2D engine, but I didn't really feel a message or a sense of bewilderment at being in a surreal world or other sort of art game vibe. That's just me though.
