The game runs well as an endless runner, but the fireball seems a little unnecessary with its current implementation. Focusing on both the dragosaur and moving the fireball around is a bit tough, so I normally just moved my mouse to sit in front of it so It would hit something no matter when it was fired. And I couldn't keep it out of the way until I wanted to use it because if a second fireball was fired while I was waiting, they would run into each other and destroy each other, making a sort of use it or lose it scenario. If it weren't a set firing time or it didn't destroy itself, it might work better, but I only really got good scores when I wasn't actively using the fireball, getting second place on the leader board with a 928(though it hasn't updated to show it yet).

The sounds are okay, I know someone already mentioned the jump sound could use some variation, but I think it might be nice to keep the music playing, as as soon as the track has ended, it doesn't loop and is gone until you refresh the page.

super fun but these leaderboard game are distracting me from coding xD, but this 1311 is to good.

I see the inspiration on this one ^^

Cool

I found the ability to randomly throw fireballs fun, and satisfying. It allows to progress more easily and makes the game more fun, imo. I also enjoyed the cool volcano intro, and the leaderboard addition making it a bit more fun and competitive. Well done!

A nice addictive little game.

I like the eruption at the beginning of the game and the leaderboard was a nice touch. I really like how when lava or a fireball hit a cactus it felt nice and crunchy, something I found very satisfying. 

I didn't find any "bugs" per se but I did find that using my mac the fireball controls felt unresponsive and almost random. I would also suggest adding some variation in the character jump sound as after a while it gets a tad annoying to hear. 

The scoreboard added a fun competitive element! It was a fun solid game!

It's a really nice game. I like the volcanic eruption as the game starts and having to run from the lava is an awesome idea. I also got the first place on the leader board (Fav score: 845). I wasn't able to use the fireball to its fullest potential but it saved me from time to time and I like that you have that ability. To improve the game I think it might be better if there was a meter to build up and then you can fire with a left click when you want

Cant go wrong with a dino game ! :)

Not much to say in terms of feedback. It's already pretty well rounded .It looks good, plays well & it even have an oline leaderboard ! (I managed to get #1 :) )

Not sure the fireball add much to the gameplay. I ended up not really using it. 
You should add keyboard navigation on your game over screen and put the retry button on first select. It's easier to get the player to go "ok just one more try" if he only need to press space again to launch another run. (for unity you can do that through code With UnityEngine.EventSystems.current.SetSelectedGameObject() and passig it the the GameObject of your button)

Appart from that, really cool game.  Great work !
