Hey, thank you so much for playing and reviewing our game.
There's 5 levels so far. It's funny you say levels 2 and 3 are too long since 4 and 5 are even longer and harder but that's valuable input. We'll also add a level selection system and some way to see the progress through the level.
Also, next in line will be some rewards for finishing the levels but we're still thinking about this one.
