I think I know which part you're referring to, and you need to use the dash move by pressing the 'd' key so you can make farther jumps.
Yeah but idk what jump because theres two areas where i'm going (fairy spawner and fly spawner) that gives you a upgrade when you make it past both
I literally can't find anything on this game and I want to proceed
If you go back until you see a plank you can jump on, go up and you will see a lever, pull that and this gate will open for a limited amount of time. Simply dash to it before it closes and you should be good.
Yeah I already got down there I was just missing a very simple part thanks anyway (I had to do the jumps at thew bugs)
