Started first time, no worries in MirageOs on my Ti-84+

For anyone who wants a great game in 3-D, this is a great choice!

Gameplay - 9/10

Easy to start off, reminiscent of DOS-esque Doom games in movement and style. Not much to complain about, but enemies seem to blend into the walls occasionally.

Graphics - 10/10

First class graphics, at least for a calculator that is!

Reasonably smooth, may be irritating for some people but you quickly get used to it.

Ease of use - 10/10

Opened without a fuss, controls are well laid out and are easy to use. Reference of the manual was necessary, but i do that anyway with all games

Depth - N/A

Havent gone too far in, so not much to say here

Overall score - 10/10

Gameplay: 8/10 The controls are easy and responsive, the many guns are cool too, but the aiming is tough. You'll find yourself running into the enemy just to shoot; the enemies’ great AI also contributes to the difficulty.

Graphics: 9/10 The beautiful wall textures and great enemy animations are a major game complement, but the enemies and Items can really be hard to differentiate from the walls at times.

Controls: 10/10 Easy, fast, and responsive. Great controls.

Bug freeness: 10/10 No bugs at all

Graphics: 10/10. As high a frame rate as “DOOM”, and much better wall textures. Also, the game has different kinds of enemies and guns, and keeps track of separate images for all of them.

Gameplay: 9.5/10. This game is very confusing, starting at about the third level. Before that, it's relatively easy to keep track of where you've been. Five kinds of weapons to have (including a knife) keeps you interested in slaughtering the aliens with phasers.

Originality: 9/10. “Gemini” has better gameplay than all other shooters I've played. Almost top marks.

Requirements: 9/10. Unfortunately, this game takes up 23.8K of your memory and only runs through MirageOS. Fortunately, it's worth every byte of that. It works best on an SE or 84+, where you can archive it easily, while Mirage archives and unarchives it automatically when you play. This means that you'll have to archive everything else, though.

Graphics: 10/10--It's 3D and very realistic. It also has a high frame rate.

Difficulty: 9/10--Unfortunately, this game is VERY difficult. You go through this maze of rooms, and you probably will get lost. But if you are patient, you'll get to learn the layout of the rooms fast enough.

Replayability: 10/10--This game is totally replayable. You can replay “Gemini” several different ways, since there are multiple difficulty levels.

Size: Unfortunately, “Gemini” is quite large. I recommend you archive all programs and each appvar that can be archived. (Some applications don't function correctly when their appvar is in the archive, so pay attention.). In addition, you should delete all variables--who needs them anyways? (I'm supposing that you've finished all your math and science homework before playing any calculator games).

Complexity: 10/10—“Gemini” is very complex. You get five weapons, ranging from the default one, a knife, to the plasma gun. As I've said, the room system is very complex, though sometimes it is overwhelming.

However, the game itself is lacking. The idea of finding a locked door, then going through a massive maze to find the key and trying to find your way back is original enough, but the mazes are way to big and it becomes more irritating than fun. When you beat a level, you feel more relieved than happy, demonstrating the toughness of this game.
