Nice little game. I found that the visuals were pretty cool in their simplicity, and the music was fun. I would have liked more difficulty as well, and like other players, thought it was confusing to have the game screen not fit the browser, not sure if it was intentional or not, I mean, if you don't zoom out it kinda increases the difficulty. Nice one!

Good  job GGG,
Sailed through but it's nice to have something that didn't make me swear at the PC for a change :)

Well, small problem however I had to zoom out to get the whole screen. Simple game, not really difficult, I was expecting more difficulty on the last two levels. I also found the hit box of our character a little wide. Good game!

Nice. The only issues I had were that the game took up a lot more than my screen displayed, so I had to zoom out to be able to see anything, and that I didn't understand that the enemies sight range was the black square so I tried to do things a lot more cautiously than I needed to. Also, I think the difficulty ramp was a little low. I think you could have jumped to the difficulty of the fourth level after the first level.

Really good game, it remnds me of the fake mobile ads about this concept, but you made a mobile game concept really work.
