Nice simple main menu and the instructions were good, I enjoyed the little story tucked away in there and the little house symbol was nice and intuitive but I didn't like the mixture of caps and lowercase in the story. I also feel as though some BGM would have improved with main menu but it was still good without it.
I like the background with the clouds and the other blimp's but felt as though they could have been better, if they wern't used as static images and moved slowly over the background as you moved it would have given the illusion that they really were in the background.
The character animation for running is good but there isn't a jumping animation or falling animation but I did really like the springy fist animation when you punched but it felt a little odd how you slid across the floor whilst you were punching.
It's a shame that the player gets stuck on walls and you can spam jump when your touching a wall as well.
I really liked the health potions to fully heal before the boss and the animations for the boss were very good but found that I could run in to him and he struggles to hurt me even when he slammed the floor and after you kill the boss he leaves behind a little black box that doesn't hurt you but after touching it a few times just kills you and it's a shame there no actual end to the level just a you win screen then you either die or press esc.
It's also a shame that there isnt any SFX in the game as this would have made it a much better experience.
Overall I actually quite liked this game even if it was a little bare bones and though it had some good potential but a lack of animations and SFX let the game down a bit.
