Not bad
Not a bad start to your gaming career on newgrounds but certainly not the best thing i've seen. A few things that I'd like to point out:
1. Could do with better sound
2. there's a glitch where if you hit a bomb but quickly get to the next room you don't die
3. Your instruction page is very vague
Aside from these poits it did keep me playing for a while to try to complete it and you have a good difficulty choice: challenging yet not impossible. Improve your graphics and sound and you will one day produce some amazing games I'm sure
