Really cute puzzle game!
Pixel arts fit so well each other.
And I love how you make use of the tongue in different situations.
There’s one minor nitpick.
In the last level, the first move you do is go down.
But if I do that, I can’t see the top-most rock even if I go up higher.
This results in blind tongue jump, if you haven’t seen the rock before.
The same thing applies for the bottom-most rock too.
I wish the camera just moved with the toad.
Oh, and I found that sometimes the box doesn’t undo by pressing L, when messing around the earlier levels.
Is it intended, or is it a bug?
