When creating a game, it is important to realize that just because you have an original idea does not mean that it's a good one. While this was an original idea, it wasn't a very good one.
I'll start off with story line. I doubt that you were going for a serious story line, but at least put some kind of effort into the story. I mean, you almost made me leave with the introduction scene. "warrior from a village" Oh boy, never heard that one before. "someone he loves is kidnapped" Wow, this storyline is brilliant, I can tell that lots of effort was put into it. Not to mention the animation quality is horrid, and the character design was sloppy. If you want to hook players into your game, you can't just make a lousy introduction scene.
I'd be willing to bet that you spent less than an hour on the music. I've taken a whack at making 8-bit songs and I've made songs with similar quality in less than 10 minutes. The songs aren't good and are too simple. You might as well be playing Twinkle Twinkle Little Star in the background, because the music didn't help with the mood at all. As a suggestion, I would have recommended some kind of music with a more adventurous feel to it. I would look at early Sonic games.
The pixel graphics are really starting to get overdone. You're not really bringing anything new to the table graphic-wise. Pixel graphics are a way of saying "I'm too lazy to put any work into making a video game, so I'm going to take the easy route and just make pixel graphics." What's worse is that people actually enjoy that crap. I'm not asking for super realistic graphics, but I mean at least try, especially for a platform game. At least have some kind of art style, something like Yoshi's Island.
Okay, now to get into the actual gameplay itself. It was boring. I had no fun playing it at all. It's a platform game where you can only jump. Why did you think this was a good idea? Removing an element of a game does not make it better. Then the whole stone smashing thing was introduced and it wasn't really like "OH WOW, THINK OF ALL THE THINGS I CAN DO WITH THIS" but rather kind of a dull surprise. Not to mention the controls were done horribly. The sideways sensitivity was way too high, I moved too far constantly and any level that required me to do even a slightly accurate jump had me trying over and over again to get it right.
The only thing that I can imagine that might have saved this game is comedy. If you had actually given me at least ONE thing to look forward to, it could have been that. In fact, you passed up the opportunity to have comedy in your game. Because of this, you're missing major story elements that could have been clarified.
- Why does he have stone legs?
- Why is she getting kidnapped?
- Why does the village no longer exist?
There's more but I won't get into those.
I'm not trying to butcher your game here, but I would not recommend making a Stonelegs 3. I don't know how you could possibly save your game idea here, but if you can figure it out, go right ahead. It's clear that you have the opportunity to be a good game developer, but you definitely need to COMPLETELY reconsider your approach towards making games.
