I'm not entirely sure about what the problem is, but you can hold space to jump higher, otherwise you can't reach the platforms. I should probably have said that in the tutorial.
Thanks for the tips, they will come in handy. I really had no idea about how to package the game ( I wasn't even sure that it would work on other people's computers lol), but I will look into it for my future games. I appreciate your interest in the game, I just kept the art style as simple as possible so that I could focus on programming. It is possible to beat the game, some jumps are impossible if you don't rearrange the platforms by pressing tab and changing the mode, which lets you go up and down and push platforms around, if you mess them up they get reset by going in and out of platforming mode. There are only 5 levels though, and they are pretty similar, so you're not losing much.
