-Graphics: 8/10: Graphics in “Contra 83” are very good for BASIC, considering the fact the game doesn't use any ASM utilities and they load pretty fast.

-Gameplay: 9/10: While the artificial intelligence may be poor in “Contra 83” (enemies won't move at all) and there are some noticeable slowdowns, it has a reasonable difficulty level and many features. Also, a boss guards each level, and you must develop some tactics to defeat him.

-Controls: 9/10: The controls are well chosen and you don't have to go to the readme to figure out how to jump, shoot, etc.

-Replay Value: 10/10: This is a very addicting game. Be warned! If you download this, you will probably not be able to stop playing :).

Gameplay: 9.5/10
This game has the best gameplay that i have seen in a TI-BASIC game. The controls are really easy, and there's not much of a lag, even on my non-silver edition. The character moves quite fast, almost like in ASM. There is one problem though, and that is that you can move through vertical walls. This can be quite annoying. That's the only reason that I gave it a 9.5 and not a 10.

Graphics: 8/10
The graphics are alright. It doesn’t matter that the character is only 5x3 pixels or that the levels are made of lines. The graphics are great for the purpose of the game, if you consider how fast it is and that it is written in BASIC.

Replay Value: 10/10
First, it can take quite a while before I finish this game, I've been playing for 1.5 hours now and I'm still in level two. Second, because of the difficulty levels, you can beat the game on easy first and then play on higher difficulty levels. Third, when the level editor is done, you can make your own levels and play even longer!
