I didn't know what to expect of this. I think the best part was how the gameplay was layed out. You could really go anywhere you wanted with this. It could have had better animation, but still enjoyable. I really liked the music and sound effects. I just think it got a bit too repetitive.
You went to the same guy for every battle. The yellow guys reminded me of the alien from "Alien Hominid". What's that thing's name anyway? I am surprised there was not a Skip option at first, but it came up eventually. Seems like you would have one on a cutscene instead of a tutorial.
