Thanks for playing and the feedback. The visual timer makes sense so I would make it an option or default after playtesting for sure.
The logic bugs.. I can't make this up, the retry fails to reinitialize the level and I changed the levels array and challenge level on the last 15 min of the submission.
I put a post-mortem message on the game description, on the submitted build you literally can't complete the game hahaha, level 25 is 1 index off, same with challenge starting on -1.
And with the sound I took a really simple loop 8 sec, couldn't decide on the music because the 8 bits style is way too frenzy for the speed of the game.
I'm gonna update it after the jam, I learned the hard way not to change something that important at the last minute.
