Great implementation of the jam theme! Contrary to some of the comments on the non-jam page, I thought the rule discovery process was quite fair. Early levels have only so much you can do before getting the visual confirmation and it shouldn’t really be possible to get too much further without passing the knowledge gate. From a tutorialization perspective, level 3 might benefit from a tweak to add resistance to achieving the correct setup among seemingly arbitrary options. If the player locks onto the “almost” correct rule in level 3, they might completely miss the relevant detail in level 4. Again, I think everything is quite fair as-is; just considering where some of the aforementioned comments may be coming from.
