Fun game! I managed to beat all levels before it looped. I decided to play it pacifist and I'm happy to see that it is possible to do it.
It doesn't seem to be possible for Blub to obtain freedom since the levels seem to loop...
For a game like this, I don't consider random loot to be something good because there's times where if you don't have a certain item there's no way to win so you have to retry until you get the item from the chest you need to beat the level.
Overall a fun short game ^^
