I'm a big fan of platformers in general and I do like this one! Great level design, good costumes to choose from and the controls are perfect. I got to the end and got 1000 points on the 3rd and 4th flagpoles. The hazards and the enemies, particularly the death animation and how it bounces you up is awesome and I loved it when the rocket took off. If you take the game further, I could imagine between levels driving the rocket in a shoot em up style level. Some things to improve the current game would be having a solid sprite on the left screen at the start to stop player falling off, making the enemies not solid when they die and giving just a little more headroom on the double saw blades to make it a little easier but is okay as is though, overall great job!
