The visuals were great and I found the little fire guy to be very charming, and I also liked how small you felt while exploring a big area, but I agree that more things could be packed to create more gameplay per second since you're mostly running back and retracing your steps if you mess up, which disrupts the flow of gameplay. Games like these are usually best designed as "quickly die, quickly get back into it again" etc. I may have died more often because the game due to the amount of motion blur was pretty hard for my laptop to run, so keep that into consideration. And maybe using the fireballs during the parkour, not just to remove obstacles, would be neat too. Overall, it can definitely be expanded on, and it's a cute concept.
