I'm currently working on a shmup which lets players build bosses, which are then put on their profile on the website, so that others can challenge them.
The current state can be found here:

In the game ('Play'), use the arrow keys for moving, Z for shooting, hold down Shift for precision moving (pretty much the same as Touhou's keys). For using the editor you need to make an account and login. In the editor you can place turrets, which can then be sequenced in the edit tab. The sequencer has 3 sections on the little red bar, corresponding to the life stage of the boss. Each of the eight big blocks under it correspond to blocks of time within that life stage. Each time block is 4 seconds. If you want to have a better idea of how it works, check out the test tab. Also make sure that you have your turret selected (it shows tools for moving) when making changes in the sequencer.
I am curious to see your responses to it's current state. I still have a lot to do and a lot more planned to implement. Any suggestions are welcome!
Also, I am looking for more artwork to implement into the editor and the game. The player plane I made is not so nice, imo. The rest of the graphical stuff was made by my sister

If anyone wants their work included (and, of course, credited), then send me a message
