This was very charming! i'm (not) very smart and managed to not realize that there's a run button until accidentally pressing it on my about 20th try on getting that last spirit energy, lol. in hindsight, fairly obvious though, and impressed that i never thought to press it earlier
got all(?) 12 (at least thats what the end-screen reported the number as) energies. yelled "that's video games!" to myself when i found the spirit on the first screen. great stuff, video games forever
