Criticism -
The level was a bit hard to complete as you naturally want to collect all the coins from the start and then move further back into the level, but your jump is limited by the coins you collected earlier. Some jumps are also pretty hard considering that they have spikes on all sides makes them really hard.

The art and parallax were super nice to look at and made playing the game chill and enjoyable. I also liked the indicator that told where the player was when they went off-screen.
