Graphics: 10/10 - Nearly flawless greyscale that hardly flickers at all. Excellent menu and the peices are drawn nicely as well.

Gameplay: 9/10 - Great gameplay, but every now and then you have to press a control multiple times or hold it down to get a response. I love the choice between 14 and 10 row grid size and like the automatic level-up feature.

Controls: 8/10 - In my opinion some of the controls are odd, like using "graph" to exit?? why not use clear or mode?

Size: 7/10 - It is pretty big for a Tetris game: about 10k (10,000 bytes). Seems kind of big to me. There are ups and downs to this. A bonus is that (since it's a MirageOS program) it can be run directly from the archive memory. Downside is that archive memory runs short on TI-83's and 83+'s really quick.

Graphics:10/10 Great grayscale graphics

Gameplay:9/10 It's a fairly faithful clone of tetris, but the grid is 14 rows instead of 10

Controls:9/10 2nd as well as enter should be used for the menus. There is no way to quit the game without losing, and once you lose the game is closed.

Size:5/10 10k for tetris?

Overall, I like this game just because it is grayscale. The graphics are excellent and the only reason this game is better than ZTris. The only problems I have with it are the grid size and slightly awkward controls. On a non-silver calculator, the size of the program may be an issue. Overall, considering this is a BETA and according to the readme, some issues will be fixed, I would give this a 9/10 and reccomend a download. Change the grid size, optimize the code, and fix some of the issues (high score table doesn't work yet) and it will be a 10/10 and a must download. Good job!
