I was not expecting that challenging of a puzzle for my first review of the night. After about 1 hour I finally solved it and felt incredibly accomplished. Great Job!
Art & Sound
The art in this game matches the vibe perfectly. The simple color palette is very appealing. The sound effects and music mesh very well with the overall aesthetic. I loved the use of the frog as the main character for a jumping puzzle game.
Gameplay
The movement was very simple and familiar, but without reading the description it was very difficult to understand what was going on. After the first 30 minutes of struggling, I finally figured out how to really use the two tab mechanic. The guides in the game try to help convey the mechanic, but they didn't make a lot of sense until I accidentally got it to work the way I wanted to. After figuring out the mechanic, the guides made a LOT more sense.
Design & Difficulty
The design of the puzzle is both incredibly simple in concept, but still very difficult. I can definitely see this being among people's favorites if the genre is something they like. The items were very intuitive, although I frustratingly misused the block on the first try because I accidentally hit down. The two-tab mechanic, while confusing at first, is a breath of fresh air with how unique it is. I have never played another game like this and thoroughly enjoyed figuring out how everything worked.
Conclusion
An excellent game, well thought out design, incredibly unique mechanic. I look forward to seeing more from this creator.
