Thanks for the feedback! :)
You probably don't suck, it is a pretty challenging game. That's on purpose, because we feel that's a staple of NES-era games. Though we did put some checkpoints in to make it a bit less punishing. And once you get the hang of the mechanics it gets a lot easier. :)
If you get past the first level, you'll get a new form which gives you the ability to jump. Hopefully that's an incentive to give it another go. ;)
