Nice start. I included it in my TigerJ(am) #2 compilation video series, if you’d like to take a look :)

LOL, I wanted to play a vector boxing game, but it's a decent plat-former. 

Watch TigerJ(am) 2 - Part 3 from Tiger_J on www.twitch.tv

The art in your cover is really charming. I was hoping the game would be more like that. 

Not sure which art is yours and which came from asset packs or ripped spritesheets. 

The main character could use a jumping noise and a walking animation that looks more like walking and less like fighting. I get that he was a boxer in his life, but surely he didn't always walk like that?

Since it's a platformer, one or two more levels would go a long way.
