good concept, there's a few flaws to the controls
First of all, explaining them instead of assuming everyone played RPG Maker-controlled games would've been nice.
Second, when it comes to your enemies having the same exact reach as you, there would've been a few better ways to deal with it, by either allowing more movement/less cooldown after every hit, or, might as well, let the player hit further, so it's not as frustrating having both the enemy and the player hit each other constantly, until the player gives up and allows the enemy to finish their combo.
third, allowing the player to move while jumping would totally make the jump kick more viable. jumping altogether seems pretty useless if if the player's not able to move where they want in the air. it just seems like it's there to fill the checklist of typical fighting games.
Other than that, I'm fine with everything else. I'm not usually picky since I've seen worse flash games.
