The concept is good : I got caught longer than expected banging my head before realizing that you can reuse components : having a good '8' does not mean there's no other '8' in the game
Oh! I didn't realize you could reuse components, thank you!!
I'm still banging my head through my first Nerdle, despite being challenging it's pretty fun!
I think however that if you do use a 2nd component and it's not required it will flag it as such.
