Beat the game! although there was a few bugs, i had fun playing! there should be a postgame or a way to save, but maybe you can update the game to include those!
To be honest, late game sucks as of recent. There isn't anything to really do except level up and grow bigger. Maybe add a new location or a boss, or at least make the enemies grow according to the player's stats, because nothing about late game is noticeable right now.
