I know my comment will be marked down for criticism, but I would appreciate a rewrite of the instructions and such in better English. Normally I don't nitpick about grammar but the instructions are important to understand. Vote on Down!
14 years old or not you should still have a much better grasp of grammar and spelling. For your age and experience, however, I'd say it's a good start for the game, but you still have a lot farther to go. Practice, practice, practice!
For one thing, friendly fire sucks. There should be an option to turn that on/off. Second, why does it say that if you go back to the main menu, all progress will be lost but your character's stats will not? You still start back off where you were. Would be nice to go back and replay earlier levels to rack up gold and buy upgrades.
Just as a suggestion, I think with the dynamite once you upgrade it to a certain point you should be able to get the ability to self-detonate it instead of rely on the timer. That way you don't have to practically be on top of the enemies to lay one down and wait forever for it to go off.
