This game could be improved by making each image one long snake, which would make things a lot more challenging, by not allowing the snakes to overlap one another or themselves during the solving process, which would make things more challenging and be more reminiscent of the classic games, and by making keyboard control automatic instead of making us click on each new snake.
When you make a game that requires precise jumping, make that game allow for precise jumping.
There is so much lag I can't possibly play this the way it was intended.
I love the concept, but I think a more stimulating game would be to give us limited worm and have to touch every shroom while finding the hole, instead of giving us too much worm and having to find just the right pattern.
