Rlyeh has released his unfinished game to the public. In fact it is only a technical demo, but read the author notes:

I have been not coding lately since my broken relationship. But ah… life is going better after all. I think it is time to release my unfinished and dropped game as a proof-of-concept binary (nachoyague has to drawn about 2000 animations yet… btw any graphician out there?, huhuhu :). I haven’t touched the sources since February, and it was a two weeks coding work. Enjoy the water, the shadows, the reflections, the gazillion of sprites, and all that… btw, there are two eastern eggs which change the background and light conditions (only tested with BLU units).
