@Wesley, you are right I do remember thinking that during the development of the jump feature but ignored it because I found myself putting a lot of time implementing that. Apparently jumping in 2d side scrollers is a little tricky... but yes I could fix that.
Friends didn't like how there weren't any lives but it's part of the game. It's meant to give it that retro style feeling where games are hard and if you mess up you have to restart (battle toads was therefore mentioned as a result haha)
