Geometry Wars is an excellent game that has kept my interest ever since I downloaded it several weeks ago.

The controls in game are well done. It's dual stick, so you can fire and move in two different directions, which is very original for calculator. I personally use the d-pad for movement and find the XT0N configuration confusing, but different things work for different people. The buttons in High Score entry are a bit confusing, however, since you press Enter to save your score and then 2nd to get back into the main menu.

The graphics just look great. Enemies move fluidly, bullets are clean, and those explosions are just plain awesome.

A fair word of warning: Don't run this on a TI-Nspire in 84 Plus mode! It will crash, and the only way to get your calc back is to reset the 84 Plus archive as well. But it runs like a charm on the normal 84 Plus and the SE.

Geometry Wars is a great game.

Controls:

As explained in the readme, Geometry Wars was made for the Xbox. That means it uses two analog sticks. Therefore, you have to use the square centered around X,T,O,N for moving (or the d-pad) and the square centered around 5 for shooting. The controls are a bit weird at first, but you get used to it in the end.

Speed:

On my TI84+/SE, everything was quick.

Gameplay:

The shooter is quite fun, even though I am very bad at the game. Sometimes the controls made you die, but it was mostly fine.

Memory:

I don't care about memory. That's because all my programs are archived and I can run them archived with Calcutil. Calcutil allows you to run programs off archive without unarchiving them.

Gameplay: Very smooth as well as smart. 9/10

Graphics: Fairly good. I like the way the screen looked, with everything black but what was important. Though the enemies are shapes [they look kind of cool though] so 8/10

Speed: Really fast, 10/10

Resources: at 8 kilobytes, its not huge, but sure not small, Still, for the most part, its very worth it. 8/10

Controls: Excellent, the shooting was very unique with the number pad, and very simple to move [arrows]. Great job with the controls!

Enjoyment: Really fun. You may not think it at first, but it is a lot of fun.

Originality: There was a good amount of originality, mainly with the controls. It was similar to asteroids type games, but a bunch different. 9/10

Ease of Use: Very easy. 10/10

This is probably the most demanding and intense game available for the TI83+. It has controls that are unique in the 83+ world: basically, there are 8 buttons that control ship movement and 8 more buttons that control shooting direction. As if that isn't enough, you get to press two direction and two gun buttons at a time, allowing for intermediate directions. I find that this control system makes the game more engaging and fun, but I can easily see how others might get frustrated.
