Not too bad...

But there are a few things that bother me.
- The control setup is very bothersome.
- There should be an animation once you get a line cleared.
- It's not much different from the actual Tetris content wise.

Average Tetris remake

The core game is good and mostly problem free, but does have drawbacks and doesn't add anything that wasn't in the original Tetris. The game lacks both sound effects and music. Graphics are decent, but static. There is no counter for how many lines are cleared, only level and score. There is no customization (modes, difficulty, hide next piece, etc.).

More importantly, if a piece such as an L block is near the edge of the board, it becomes impossible to rotate it without moving it away first, which would be a significant problem at higher levels.

Overall, it's just Tetris with most of the options stripped off.

Good Start

This is better than most tertis games I've played. It's simple and to the point, and doesn't try and add any needless bells and whistles. As for ideas on how to improve it, I would make some sort of quick animation before the lines go away, such as having the line flash briefly. Also, I wasn't able to rotate blocks that had already gone as low as they could go but weren't down yet, and unless the block was in the right place I wasn't able to rotate it. Aside from those things, it's a good game.

Not great

No sound, dull appearance, and it's just classic Tetris - not even a hint of a twist. I just can't find anything to interest me here, but you get marks for function since at least it seems bug free
