I played through the game in it's entirety , I must say that I thoroughly enjoyed it.Despite that it may seem aimed at younger audiences I liked the warm and colorful graphics and the shading and wouldn't want to see you change your style.Overall I feel your game is a wonderful product , the graphics are appealing , the music and sounds are pleasant , the controls are smooth and easy to get acquainted with and the experience in general is worthwhile.The difficulty was a bit on the easy side , at first I had worried over the availability of extra lives but when it came down to it I didn't actually die.The dragon coins and blue gems were reasonable , I was able to find most on my first run through but a few of the area 2 levels I missed some and had to run through a second time.Generally the only real fault I have is that I was left wanting more , not a bad thing really , I just wished there had been more content and levels.Some of the things I would love to see in such a game would be more levels for starters , a lot more , perhaps eight worlds if possible , that would be long enough for me to feel fully indulged but not so long that I lose interest.Along with additional levels bosses and mini bosses would naturally come into play , but something else that would be cool is if you were able to find secret or hidden exits in some levels that may lead to shortcuts , alternate routes , bonus levels or various other secrets , maybe even unlockable alternate colors or a hat for novelty purposes , even though I like blue.Greater enemy diversity would make it more enjoyable as well , even if you have more than one foe that serves an identical function , just the different form would offer a bit of diversity.Maybe more upgrades or even the addition of temporary or single use items that take effect at the start of levels , just to give something to spend gems on other than lives after the upgrades are obtained.More breath weapons would be interesting as well were that a possibility , maybe if there were an electric breath , it could pierce enemies or have minor seeking capabilities or just longer range , I think it would be cool at least.The storyline worked well too but were it a bit deeper with more scenes during progression that may make it a bit more engaging , I'm not entirely sure with that one though as your storyline worked rather well as it was despite simplicity.Also I noticed in one of the blue gem challenges there were fireballs coming at you much in the fashion of Mario games when they approached Bowser.I found that element interesting , a regular level that incorporated such would be interesting.I know you have falling platforms but maybe you could add tilting platforms somewhere too.I think that's about it , that's my opinion at least.Personally I found the game rather fun and will be looking forward to your future works , even if you didn't try to make improvements or adjustments I would still want to play the next one , it's plenty good as it is.Hope to see more from you in the future , were the game bigger and had more content it would be something I'd be tempted to actually buy.All in all , good job.
