• It is misleading for the web version to have a Quit button
• Does the web version have SFX? I didn't hear them
• Coins would benefit with some particles effect when you pick them up
• The fade-out of coins maybe could be a little faster? Right now I need to wait for a second or two to know if my coin has been collected
• The jump pad could sell its purpose a little better maybe? A simple arrow pointing up would be nice or maybe a different shape? Check how they have a spring for a jumping pad
• Teleporting player to the next level maybe should be with some kind of animation of him getting in, or just disappearing when he touches the teleporter(end level)
• I know that your levels are not very long but maybe add checkpoints if you want to make them larger? :P

Bugs

• Sometimes when I jumped near the enemy it would kill me anyway, maybe scale down the trigger box a little bit?
• Sometimes my player would be launched in the air when walking down the stairs when an enemy is lower but the enemy would not be killed

I've only played through the first 6 levels but not to look like I hated the game here are the things I liked( also I was a QA Tester, soo most of my career I just pointed out mistakes to people soo don't be discouraged)

• Jumping felt really good
• enemies falling from the platforms above are a great addition to the difficulty level
• Jumping off enemies is a nice addition, maybe add some coins to places where you can only go via jumping on the enemy head in the right time?

And overall that's a nice game :)
