When you saw Pokemon, you probably thought this a horrible attempt at trying to make Pokemon.
If so, you were right.
This is a horribly failing demo of Pokemon.
The author does not even have the first event implemented in the APP. If the author was smart, they would either give up on trying to cram it into an APP, or they would include the game's source in the zip file!
You walk around and read signs. If you walk into the grass and encounter an enemy, it is always Caterpie! If you leave Pallet Town you get an error.
Maybe I'm being a little low with this, but if you are going to put it on the graph screen, try something besides ASCII graphics!
Decent, but I ran it on a TI-84+ SE, so....
This is a bad game, but keep in mind it is a demo.
