Good job on the game man. I really enjoyed it. For me the beginning part was a bit hard, because I fell down on the spikes quite some times. I don't know if it is me, but that part gave me a headache. Other than that everything was great in my opinion.
You managed to make enemies annoying, which is great in this type of games ( talking about to laser eyes and bomb thrower lizards ).
Hope to see more from you :)
