Here's my feedback:

• Adding an effect to changing size might be a good idea , making it randomly timed is kind of awful though
• You can add like flashing lights to character to warn the player that she's gonna shrink / expand
• sometimes the double jump I don't know why ( even though i tried with full size and small size)
• There is a tile near second key that has no collisions and when i stand on it i fall and die ( not the one that leads to chest)
• there is a key that's in the middle of the tiles I'm not sure how to get it
• The coin sound effect becomes very annoying after taking a couple of coins , maybe add a different effect or increase pitch according to how much coins you took
• The pixel size is inconsistent and you should have drew a smaller sprite with same pixel size instead of just decreasing scale by 2
• The losing text is kinda weird that it's made by ai , it's not crisp at all and too large
• The back button keeps changing position with the player which is kind of annoying
• The background is kind of blurry and doesn't loop around which is what parallax background are supposed to be
• since double jump lags sometimes you can do a triple jump
• The first tile with the key has tilemaps with collisions that aren't correctly set and are very annoying to deal with

Good job overall on your game.

عمل رائع بس التحكم صعب شوي 🌟🎮 شوف لعبتي يمكن تستمتع فيها 🙏

Nice game but difficult. If you could reduce the difficulty of the game it would be better.
