Thank you for the valuable advice, it’s really helpful. You’re right about the scoping issues (feature creep) is a real struggle for me. I actually failed to finish my last two game jams because of it. Luckily, this jam gives us more time, so I should be able to complete it. As you mentioned, focusing effort on core gameplay is what matters most.
Also, I realized that making 'piece rotation' an upgradeable skill might have been a design flaw, as many players seem to miss it. Thanks again
