I have the first three, Deadhead, plaguebat and fireflies, but am missing whatever goes in the fourth slot. has anyone managed to find it?

Hey! If you have ideas or suggestions feel free to share them with me here. Thank you.

Apparently, if you take a screenshot, it also opens a developer tool when you do it. Im guessing it is mapped to this key too? If the developer can change the key for it, or if someone knows how to make it so it does not pop up everytime i take a screenshot, it would be nice. Thank you for reading. NOTE: I like to take screenshots of games....

am i missing something here? This looks exactly like a ripoff of hollow knight....

it seems i have encountered a bit of a problem. Those locked chests, can someone give me a hint as to where the key to these chests lies? (just to make it clear. I don't want to hear exactly where it is, i only want a hint as to where it may be hiding.)
