Very fun little game, it's too bad there's only one level.
There is a problem with your credits, however. If the works you used weren't CC0, you need to state the name of the work as well as the license in the credits, along with the author's name.
Also, you seem to only have five assets from OGA? The rules say you have to have six assets.
Either way, keep up the good work! :)
Thanks!
