I really liked the concept of the game, I had fun with it, but the execution of the idea ends up harming the experience.
The first few levels propose an interesting experience, but as soon as cycling enemies are introduced, the experience starts going downhill. Since you can’t see these enemies, you just have to hope they are in the right place, because sometimes it’s impossible to go past them optimally. Other levels also have leaps of faith, where you will have to jump down a big hole without knowing what is at the bottom, which often ends up in dying. The lack of coyote jumping also makes some jumps annoying. It would have been nice if I could restart the level by pressing Space. And finally, on Firefox, whenever I press the Spacebar, the website scrolls down, making it impossible to play, I had to switch to Chrome to be able to play it.
