This wasn't a bad platformer and I enjoyed the parts of the game that had puzzles to solve as well as the addition of boss fights.
However, the game is difficult to look at. It feels like everything in the game has a different art style; the chameleon, turtles, snakes, doors, platforms and ground all seem like they belong together but background elements like trees, water, fountains, etc. look like low resolution versions of assets from another game.
It's strange that snakes, birds and bosses have animation but the chameleon doesn't. If you can it would be a good idea to add some kind of walking animation to the chameleon, something simple to one set of feet in front and then the others.
The music is overbearing and it wouldn't hurt to add a mute button to the game. In addition to the music the game lacks sound effects. The game would be so much more appealing if it had some sound effects for jumping, shooting, grabbing with your tongue, switch pressing, water sounds, impacts to enemies, impacts to the player, and victory for reaching the door.
Despite this, I did have some fun playing the game. I hope you'll continue working on this and make improvements to it.
