Thanks for playing! The game unfortunately doesn't say this, but it is on the itch.io page: Pressing I opens your inventory (with what you're wearing and with the stats they have )
Also you can hold block, there is no max block time, just a minimum.
The enemies scale with the room count so they deal more damage in higher rooms.
Dying should only happen when you get hit by an enemy.
PS: nvm I forgot to write how you open the inventory. Now I feel stupid. Thanks again!
