As @ermac98 mentioned, you shouldn't really show this project to anyone in this stage yet. The drawing you posted on your page is frankly much better if you want something to show to people.
Some notes this game – apart from not being finished, and from using placeholder art:
– The regular movement is too slow, running is almost too fast. I'd pick an average between these two and stick with it, otherwise, people will just hold Ctrl for the duration of the game
– Why does the dragon have to turn to face you whenever you stop? Wouldn't it be better if he kept looking in the direction he was going?
– No animation when sending a fireball.
– Fireball trajectory looks a bit too unpredictable and also goes in the same direction no matter what – even if you're walking left.
– Falling doesn't restart the game.

And so on. There's not much else to work it at the current stage.

This isn't just not finished, but also barely started. I'm not sure why you would want to show this to anyone.

I fell off the map at the first jump but the character didn't die. The camera still follows the player along the X axis even though the player is off- screen
