The first two things i did in your game was clicking by mistake the quit game button and had to F5 the page lol. And after that, i missed click on "E" Key and discover i can skip the level i blocked on to continue the game and beat later levels ! I felt like the Quality Assurance tester getting inside the game and access god like powers XD
I enjoy a lot your game, its simple but very clever and the levels design is on point ! Chef kiss, or more like Dog bite in the tail/butt ahah !
