I'm going to go ahead and guess that this comic is about a person trapped in their Pokemon game and the only way to get out will be to 'beat the game.'
Seriously, this is a cliche. If that's not the plot, then go ahead. Fix what Mobile Tsk said, possibly get a more creative hero sprite, stay away from multiple staircases in a row (A grand staircase, maybe, of multiple fused together), and work on the plot. So far, it seems to be taking the above direction. Nothing turns away people like a dull and/or overused plot.
