Very difficult, but once you persevere, it's fun! I got stuck on level 12 when playing on Normal, so I switched to Easy and was surprised at how subtle the difference was, but it definitely helped. My brother also played through the game on both Easy and Normal, he did very good: he managed to beat normal with only 453 deaths! He loved the game and wished to see more! It'd be awesome if this game had sound effects and music!
