This was a very cool game with great mechanics. Just like other commenters, I’d suggest to add some explanation on the itch.io page (you can still modify it) because otherwise its a little confusing. Like, mention that there is a timeout for placing cannons, that the castle needs to be surrounded by cannons to work, that there is a reload for cannons, etc. I also wonder if it could be made so not all the cannons fire at once?
