were you doing this in hurry, just wondering. Theres many errors, invisible people (like my invisible rival which gets a Bulbasaur out of nowhere), inbalance (mainly fighting ice pokemon when the only choice you have as a starter is a fire pokemon with ember as a move.) Many maps are mediocre as well, I know the theme of the game is for digletts to wreck Kanto, but I mean the caves, and other 'new' outside areas just seem sloppy. Is the ice cave supposed to be mute? However I feel it can be fixed. First, TEST everything. If there is a bug, fix it. Make sure you don't level up too fast. It doesnt matter if this is a beta, betas are supposed to give the impression of what the rest is of the game is going to be like, and if you don't bother to fix the glitches or test, many people will assume thats what the final version will be like.
As for now, your hack gets a 2 out of 5.
