I enjoyed the authentic retro vibes of your game. It looks and feels just like a game made in a previous century should. Visuals and sound are cool and fit one another well. Mechanics and gameplay are straightforward in their base, yet have a lot of depth. It feels the right way, how the challenge slowly develops as you pass from one scene to another.
I only had some issues with controls at the start. Nothing to do with the game itself, though. I played in a browser, and the controls were slightly different from what is described on the game page.
