good, but lackinng
this is a good, fun game, but too simplistic if you want my opinion. Weve seen this kind of game before in flash form, and more than once - yours wasn't the best.
see, what you need is a few more powers , at least some authority figure (government, cops, aliens) to try to stop you. What you DEFINITELY need is an ability to make combos of some sort, like many punches in a row or a few pushes for an extra cool attack. Also, in a sequel, include at least one more monster , so you can choose between the two.
