Looks nice but yours looks better.
Thank you for your kind words!! It really motivates me to hear such a thing!
I just had a look at it, while the stem concept is the same (Mario Maker), I believe mine is more organic as I'm putting a lot of personal effort into it, every bit of code has been carefully written by hand.
The first release will be (if not, almost) freeware, probably something like 3 or 4 worlds, each holding 2 or 3 maps to explore. It may or not include the level designer.
I want it to be a test product, presented as a final one. This way, if it suffers severely bad reviews, I can always pull it off the store.
The current graphics aren't final, as some of them are (probably) copyrighted. Once I get into the game design stage, I'll try drawing some of the stuff myself.
So yeah, I'm writing code for it almost every day. Even when I'm working on side-project, it's usually a "beta-test" for new code to be implemented in the main project.
I gave-up saying that it will be released soon, as I have no idea when it will be possible. I still have some obstacles to climb, physics to tweak and user interface to redesign...
Contrary to my previous project, I've learned from previous mistakes, the code is object-oriented, scalable, expandable, highly readable and maintainable, so all I can say is... I'm on the right path.
