Folder Dungeon

this game is so cool!

can I make a wiki about it? (if it doesn't exists yet)

Played it once, Heat isn't a big issue. That info gets cut off on the left is really annoying. Came from "Latest Featured Games", so congrats!

First of all, great job with the game. It is fun and interesting.

Balance Recommendation: Nearly every item could use a retool downward as power gain easily spirals out of control.

Power combos like bat + baguette can be dramatically improved simply by reducing baguette damage. Like, literally, it can deal 1 damage per baguette and still be competently powerful.

With that said, I'll do a playthrough with per relic recommendations.

*pirate hook* - This is fine as is. 
*amm_bush* - This can be devastating when applied to dynamite boy. Drop this down to 2 and it'll be still useful, but much less likely to screen clear on entry.
*lance* - This is a single-target single use item per room. Sure the player can do a leave-enter spam; but this is usually a "eh, it's free" pick up for me.
*magic hat* - oh, one of the most absurdly powerful items in the game... if there was enough keys to take advantage of it (see below)
*happy heart* - I would either scrap this or buff this. apples are abundant and serve the purpose well. As a relic, I'd say a better move is to move this as a multiplier. Say +15% health instead of +8.
*friendly soul* - This one is honestly fine.
*rusty sword* - Reasonably balanced and fair. No complaints.
*big pocket* - Oh, boy, this stacks with magic hat... 20% is fine. There's honestly not much of an issue here, but it can get glorious diving 5 chests deep into a monster.
*water bottle* - Baguette combo! This can honestly lead to humorous death-on-enter issues. Looking at it, I would've figured it be a heat reduction mechanic which is what I would recommend instead. 20% chance to not increase heat when moving rooms. Make it stack multiplicatively so it approaches but never hits 100%.
*magic feather* reduce this to 1 damage and it's perfect.
*glasses* I actually recommend a major change on these. Change this to +20% chance to find keys on monsters and chests. This pays dividends when it comes to big pocket and magic hat and allows absurd builds to flourish.
*baguette knife* Oh jeez, this is where the big problem arises, on heal is a guaranteed effect with bat, and it does 5 damage? Reduce this to 1 and it'll actually be balanced and still worth having.

Recommended items to add:
*Silver Coin* - +15% chance to find a shop in a room (adds a new room as a shop)
*Silver Tongue* - reduce shop price by 10% (multiplicative). 10 of this relic reduces shop prices to 34%. (0.9 ^ 10)
*Key Chain* - 20% chance to not lose a key when opening a chest
*Flaming strike* - while overheating, you deal +1 damage.
*Disco Inferno* - When you take overheating damage, you have a 5% chance to increase your maximum heat by 1.
