Absolutely incredible game. I made it through about 3-4 levels on Story Mode before giving up and switching to Easy Mode, and even that was quite challenging - the controls felt a little loose/inconsistent at times, which was a big contributing factor. Didn't decrease enjoyment whatsoever, although it was a little frustrating at times. Really nails the retro gaming vibe of simple but challenging levels and failing again and again until you nail it. Would love to see this fleshed out with more kinds of obstacles (as opposed to just spikes). Great work! Would absolutely play again.
