I suppose I should've asked before submitting my game, but is it okay to submit a WiP? It's fully playable as-is, but it lacks artwork and will be getting a small sandbox setting and introductory adventure added in the future (and will probably be headed to Kickstarter to pay for artwork and professional layout as well as a print version). 

I'm not The Boss of the Jam, but I'm definitely doing a WIP - posting devlogs as I go. I'm treating this kinda like Dungeon23, where I do something a day on my submission for the month of June. Who knows, might get feedback that helps me make it better! What do you think?

I see in the previous discussion, MonkeyPaws said WIP are OK!

Excellent! (Also, if this gets more eyes on a WiP, all the better!) 

Yeah yeah yeah! WIPs are totally accepted and encouraged!
