You're right that might clutter the map too much, but you could always add a legend of the map symbols and have them toggleable from the map screen, meaning the player could remove icons to see other icons, and the old icons are still there just transparent/invisible. The other suggestion is, could you add a possible exp bonus when either discovering campfires for the first time or at the very least a small buff to increase exp gains after spending a night there? My bad, the last thing is, mana isn't completely restored when using a campfire, nor is restored completely when visiting town, you only get full mana by leveling up, so I want to ask if you add mana potions or a more convenient way to restore mana, instead if you haven't got a level in a while, you would have to wait in town for some time to slowly restore mana. Sorry to add so many comments here, cuz I know it's not helpful for someone screaming at you when it's your job or dreamjob. Anyway, thank you so much for responding to my comments so far.
We have to value making the legend. We will make you recover all your mana when resting at the bonfire. We have been wanting to add a mana potion to the game for a long time. We have to find a good way to do it, since we don't have any free buttons left on the remote control.
Don't worry, comment all the suggestions you want!
