I was having some trouble getting it to work in my browser at first: I had to enter and exit fullscreen mode a few times for my keypresses to register. But once I got going, it was really fun! I love the blue-and-yellow color scheme, it's a good pick. I also love the little frog, and the bouncing feels right. He does tend to get stuck on invisible walls, but I still love him. I feel like getting stuck on visible walls is actually a cool thing: here's a wall-jumping ninja frog! It saved me from falling into the pits a few times.
Keep up the good work!!!
