Haha yeah, we thought the idea might be simple but we fancied picking an idea that we would have time to polish, as we’ve run out of time in past game jams.
We tried to make the game difficult enough that most people wouldn’t hit the 8-ish button limit we found some keyboards have—there’s actually a lot going on when we choose the next key (e.g. this expression, that reduces the keys the randomiser can choose down to only those close enough to the keys pressed by both fingers adjacent to the next finger to place)! For people with keyboards with higher key-rollover, the second gamemode challenges them to press a lot of keys.
