Cool puzzle
Deliver checkmate!!
For one, you turned the board and all the pawns are on the verge of promoting. Which implies your checkmate is not even a checkmate!

Flawed puzzle even if with board flipped in a tricky manner because the final position is met with c1=Q and not only is this not checkmate, but also black is winning!
sorry guy, I make it then I realize that was flip =))
Saying sorry won't make it right. You can repair the puzzle or delete it - those are the options!
The direction of play is now regular but the position is illegal with 9 black pawns and impossible pawn positions a5 and h5. Also, the solution moves make no sense as they are far from the best.

Deletoing it isn't an option, since it's the first post.

Indeed, you can no longer delete the first post in a topic (used to be different). But you can delete the content and add an explanatory text. It seems you can still edit posts after years (which is a bit weird in forums in general).
Find the way to give checkmate!!
