Great, a tetris clone.
Tetris Attack != Tetris
They are
very different puzzle games. It just so happens, that it's one of my favorites. I even put up with purchasing a Pokemon game just so I could feed my Tetris Attack craving! (Tetris Attack for Gameboy Color was rebranded as Pokemon Puzzle Challenge.) More info on Tetris Attack can be found
here.
To the author:
Unfortunately, as a rabid fan of the game I'm going to end up tearing you apart on this one.

Problems include:
- Poor puzzle detection. I've slid blocks to the side that have completed three in a row rather than fall down like they should. I've also managed to clear the wrong color block in a stack of 4. (Don't ask me how.)
- The graphics need work. Whimsical graphics are a key element to the game. Replacing them with simple colors just doesn't do it. I realize this is a 4K game, but even pixelated graphics are okay. See the attached image for an example of what I changed when I cloned the game.
- Chains, where are my chains? There's no visual confirmation that I've created a chain. Again, this was a key element to the game.
- Width and depth. The board is far too wide, and not deep enough. It should be 6 columns wide by 12 rows high. Anything else feels "wrong".
- Competitors. Another key gameplay feature in the challenge mode of Tetris Attack was the virtual competitor. Even if you can't see him, he would throw garbage blocks your way every so often. Vice Versa, you threw garbage blocks at him to make his meter rise faster.
- Speed. The blocks feel slow to switch. This is not a good thing in a heated game.
Again, I'm a rabid fan so take my comments with a grain of salt. (I don't even like
Crack Attack that much, and it's a fairly good translation!) I think you've made a great start, but it's really difficult to pay homage to a game like this in only 4K.
