I put a Warning right under the description that points out that there is a functioning save system and that the game needn't be completed in a single sitting. There are multiple fountains that act as checkpoints throughout the game that can be used with "J" when "?" appears above Char's head. Additionally, every non-boss powerup saves the game (but not player position). This game was designed to be a rage/speedrun game, so if you are having a hard time its because you are playing through what would be the hardest difficulty (in a full version if I ever make it)
