This game has a fun art style, and the controls are fun and simple to understand. The character are also designed great, they remind me a little of those toads from Mario. The story was also simple but that's an okay direction to take, as many games have simple stories but are known world-wide: Mario Bros and Shovel Knight come to mind.
A few nit-picks I found was that the text can be scrambled by rapidly pressing T to activate and deactivate the text boxes; and that you can gain a lot of air by jumping then jumping against off the NPCs, Which I think is not what you were going for as it does look kind of goofy. Another drawback that I think is a serious glitch, is that once you get to the upper world, you can get stuck between the platforms - and I cannot get unstuck, causing me to force the game to close.
