This is a gauntlet-style horde game. Can't say I've seen a lot of these this jam.
The mechanics appear to be implemented well, but the polish is lacking. This is likely a solo dev using asset packs.
I can tell when Navigation Agent is being used. Though there's not much else for it to do in this case, this is a reminder that it's not a smart tool.
I get the feeling that this is a dev in the unfortunate position of being in a jam by their lonesome self. Hopefully, we see you back in January, and if you do come back, hop on the Discord and try to find a team for yourself. Your skills will be elevated in that environment.
