Great game Tunmi. I'm looking forward to newer versions as well.
I agree with what everyone has posted so far in regards to new features. Items would be nice and I especially like the rage thinggy running away suggestion. Maybe if its health gets low enough it starts to run away and you gotta catch it. You could even make a dedicated mode for this, where you have trap items like a net that lifts him into the air allowing you to pound it relentlessly. Or maybe even add combos? Or in running mode you can freeze it with a freeze ray? Just some ideas. I do have to go so wrote this post quickly but I might write a more detailed one.
