The feeling is just great! I love the way the level-transitions work (even when you fail). It just adds a huge amount of charm to it. The sound really adds to that as well. Gameplaywise it’s nothing special but a good gamejam idea that has quite a bit of pre-planning and maths involved. This would probably be a great timekiller! Also I like that you always make the level-total transparent. It helps the player understand the scope and way too few games do that imo!
Well done!
