Kenney makes awesome assets - but they don't seem to have sizes listed for the tilemaps. I am a newbie - so please forgive me if there is an easy to way find this out in Construct... but I am having trouble setting the size, offset, width, etc. for the tiles. I can get it close, but not perfect.
I think these tiles are 21 x 21 but they still don't look right when I use them: kenney.nl/assets/platformer-art-deluxe
Thanks! :)
