Avoider flash. The main character needs color, and so does the bare backgrounds. Jumping over the ban hammers is too challenging due to the character's large sprite. The text in the game is not English. You should offer an English translation.

Annoying that you have to reload the page every time you die. No instructions too. Why does it take so long to load in the next level too, even though you can still move?

Edit: Thanks for adding the flag, it makes it a lot easier to play now. However, the level loading issue is still a problem, and I doubt it's an optimization issue, as this is a fairly small scratch game. Now that I can restart, I took my time to play the game, but it was over nearly as quickly as it began. The level which I quit on before was the last one. This game is really short. In my oppinion, it should be much longer. Although the music is from NCS, you should really credit them both here and on scratch. I like the variety of characters. Also the message to restart barely shows up.

Here's a way to fix your loading issue: https://scratch.mit.edu/projects/1049232462/
Take a look. Use any code you want, no credit necesarry.

Edit 2: The song is released by NCS, so there's no worry about copyright. If you want to credit Different Heaven and EH!DE, you can do so with this link: https://www.youtube.com/watch?v=jK2aIUmmdP4

The level loading glitch is even worse now with the hilly level. I consistantly got stuck under the floor. Check out the scratch link above, I think I found the fix you need. Not sure how I feel about the increased framerate.

VERY EPIC THE FAN GAME, TOP FAN GAME
