There's a lot of obvious problems with this but I'll just list what I saw.
- The web player does not fit into the space provided
- The music on the main menu is a 2 or 3 second loop and does not sound good
- The music in the actual game play is annoying and does not fit the game at all
- I can just die sometimes for no reason
- The platforms that spin around move really weirdly
- I guess there's no actual goal to this game?
- If a game does not have an end goal or objective, its not really a game at all
Hope this helps.
