Hey thank you for your kind words ๐
Yeah the right length of gamejam games is always hard to judge ๐
Some people want to play a lot of games and don't want to play your game for too long, a couple of people never saw the Boss because of it ๐ข
Level design did take a bigger chunk of my time that I expected, but I first made all the enemies and the Boss fight, so my though with the level design was to have a good introduction to all new enemy type and sprinkle the story through those levels. So apart from the the second to last level that is mostly a narrative build up to the Boss fight, all other levels introduce a new enemy type. So I assumed it would be the best minimum viable product.
Again thank you for the comment and thank you for playing ๐
