I knew this idea was going somewhere when you showed me a month ago. I really wish I wasn't busy and had what it takes for this, but even with my current experience I don't feel I could do it in a timely manor. The examples you've showed are excellent, especially that boss battle, that's some really sick work.
For anyone interested, I've worked with Millz in that past and it was good fun. We did Stabika 1-3 together, and he was veyr much involved with the design. Most artists get told what to do, then do it. Not the cse here, he's as much a project leader as the programmer, despite the generic roll of the programmer being in charge. Bottom line, he's good to work with.
I definitely think this is your best work yet; It's creative, well presented, and the ability to turn this into a full fledged game with no flaws at all is there, it'll just take some serious work on both the artist and programmer. I hate seeing the extremely high potential of this, and not having a say in it, kinda sucks haha. I definitely urge you to keep this project alive, don't half ass it. This could easily be your new hit, the game you become well known for. Even if you have to wait months, or a year, don't half ass this project, do it right or don't do it at all. Excellent work, good luck finding someone.
