I didn't do any big updates I just changed a small bug that didn't allow the title screen to appear properly and a small crash on one part, but I didn't add any content. or make it any better, so is basically the same game, i believe it was mentioned if someone needed to do a little bug fixing it was okey as long as you didn't change the core game or add any other stuff, I refrained myself from expanding the game any further since the jam voting was ongoing.
I had posted about it in my journal After release announcement - WizMech by Studio Lemi (itch.io) it was done on 22nd.
