Is there a complete walkthrough of this game?Because I dont know where to go after the 4th gym

is there a way to randomize this game?

Hey Maximal, sorry I missed your comment. There are a few youtube walkthroughs: https://www.youtube.com/watch?v=Avtqooq6NeU&list=PLU24oAdl746DOR_s92-uVKG3E3zuwEEtx
Otherwise you can ask any questions on the discord
Hey DudeCubed, got you your answer on discord. Sorry for the slow reply here. There is randomization mode on newer versions.

Patch 2.5.11 is up
Added a new MG
Makes it so that static encounter legendaries that are defeated will respawn after becoming champion
Added Throat Spray as an item
Minor text fixes

Hi, the download link seems to be directing to the 2.0 update instead of the 2.5.11
is that right or is it the wrong link?

No, that's fine. The realy version number is seen at the top of the options menu in game. The file download name is always 2.0
