Here's some tips:
- Music and voices/noises would be very nice
- Do some sort of "dying" animation, it's annoying when the character just drops to the beginning in the same second it dies
- Blocking would be good to this game, it's really hard to not to die from the enemy bullets

Anyway, this seems good, if you just practice more!

Bof...

Didn't make it very far. The mechanics of this game seemed a bit unpolished.

Hey.

This could be a very good game, but it needs lots of polish.

====================
Game Design:
====================
- Please include some audio (good music tracks and sound effects).
- Include variable length jumping.
- When you die, don't just instantly restart the game. Include some sort of pause and/or transition there.
- Shortly after passing the beams, there is this section where you have to jump down. I wasn't sure what I was supposed to do there. Basically, when you have is a "leap of faith", when the player is not sure where to go next, so they'll just jump and hope for the best. Include some indication that the player is actually supposed to go down.
- When you pause the game, make the word "PAUSE" stand out more, and change it from the generic serif to something that is consistent with the theme of your game.
- If there are power ups for the player, then I must have missed them. If not,please add some.
Please consider adding a scoring system. Players love getting points. (:

====================
Engine and Mechanics:
====================
- The animations of the characters are jagged. This is especially true on the player character's walking animation,
- When the enemy soldier fires, the shot comes from the middle of his body instead of his actual firearm.

====================
Media
====================
- Graphics need some work. For example, the "streaks" on the player character's pants were
poorly done.
- There is no consistency among the graphics. The title screen is different than the in-game environment, which is different than the characters.
- The red pools (lava?) are just solid red blocks. Please make that more detailed. Same deal with the laser beams.

====================
Conclusion
====================
Based off what I've seen, I'm going to take a guess and say that you're not an artist, and you tried doing it yourself. (: Please collaborate with an artist. If you don't want to do that, of if you are an artist, then please practice your art skills (drawing, illustration, and animation). Otherwise, please find free art, or purchase pre-made art.

On the plus side, it does look like a good start, and other than the issues mentioned above, the engine seems to be fairy solid. The player's character was also easy to control. However, this seems more like work-in-progress than a finished game.

Good skill polishing this game up. (:
