The idea to dig is cool! I really wish you went a bit deeper with it. You only have to dig once at start, then it’s a normal tower defense? I wish there was different rounds where you can dig again for resources, or change the path.
However I’m sorry, but for me the limitation is not there. Everyone is doing small games, it’s the whole idea of a game jam. You decided to ignore/overlook it, and I think it’s too bad because you’re showing you can have great ideas!
Played until the entire wave is made of dark owls, 2 times. Couldn’t get past this wave. Thanks for making it :)
