Game appears to be a Tetris variant but is actually more like Minesweeper, which is why so many people are confused by it and are complaining. As far as the game goes its surprisingly difficult to get more than even a couple thousand points, it doesn't seem to provide enough room to recover from a mistake or wait for a key shape. Suggest increasing rows to change difficulty. I find that usual Tetris like strategies of removing large numbers of rows by preparing for and waiting for a long vertical block often fails. Its unclear how the 3 shapes at the top work, so I'd add a description to the help. The right hand one when you click on it disappears momentarily and than returns, still not sure what that function is suppose to do. It might be an interesting change to make the left shape a stack related to the number of rows you've removed, and every time you use the stack you lose one. Allow discarding from the stack (but lose an entry in the stack) I found the game crashes quite a bit for no apparent reason. Perhaps some sort of memory leak? The hint function does worse than I do so it wasn't much help in figuring out a strategy.
