The levels are very interesting, and the stack restriction with the lily pad I thought was a smart design choice to restrict player movement and choices. It kept it interesting! Same for the double jump frogs! But then you give the player some agency how the frogs are stacked, allowing to circumvent those restriction if the player is smart enough. What I'm basically trying to say is you nailed the ingredients and their dosage to make a perfect puzzler, so well done!
The presentation is simple but to the point! I found the music catchy and on-theme; maybe a bit repetitive but I didn't mind it much.
The frogs are super cute, but I had this optic illusion where my brain had trouble deciding if they were frogs or birds with large tails, or birds with large ears! :D
Very very well done overall!
