Hello, thank you for your feedback. It's surprising that you didn't find that the difficulty increases, because normally the speed increases very clearly with time, which should make the game more complicated at the end. It's not the case when you play? I'm interested to see if there is a bug
It's hard to get right during a jam without some external feedback. For a game like this I would have personally gone with an endless score and brutally increasing difficulty that will become impossible in a few minutes
