It's Mario on a calculator! Awesome!
Obviously not even close to the NES which already had bad graphics, but for the TI-84+ the graphics are about as good as it gets.
Not perfect; they take some getting used to but they're not too bad that the game is unplayable or annoying. A couple jumps are hard to make but with practice you can do it.
The interface on the game is flawless. The level editor is...well, a level editor.
Lasting Appeal: 4/5
It's a fun game and it will take a while to beat, but once you do it loses some appeal. Not a lot, but it's not nearly as exciting. You can always make more levels with the editor if you have time.
This game is arguably the best game for the TI-83/84. I had played a different version of Mario before this one and let me tell you, this is the one to go for. The graphics are unexpectedly good and even the controls aren't too bad. The level editor is a nice bonus. A must-have for any Mario fan!
Note: I play this game on a TI-84+ using the most recent OS. Others have spoken of the split-screen glitch which I have never encountered but my friend did. I have the exact same OS as him. I am not sure what causes the glitch but I would say download this game anyways and pray for the best because it's amazing.
