I really like the retro feel of the game! the colors and pixel art are really nice. The concept is also pretty neat. Reminds me of the big red switch in Mario Wii. I also like how you collect coins to act as your health. But the one thing that was really frustrating was that falling off a cliff was an insta-kill. That makes it really tedious to try and play through the whole level without making any platforming mistakes. I would suggest just damaging the player and placing them at the last point they touched the ground instead. But overall, this is a pretty cool game!
