Silly little game. It was cute! I liked the art and story quite a bit! I liked the different enemy types. I wasn't a huge fan of the directional attacking. It didn't feel very smooth to play with, so mostly tried to get into neutral and attack instead of pressing a button. Another thing that surprised me was the missile staying in the scene and could hurt you more than once.
Another missile issue was during the boss the missiles would go to mid screen and stop making the left side of the screen safe to stay in. I liked the mech's art and animations tho.
Good job submitting! :)
