On a serious note, this game is definitely cute and enjoyable to play. However, sections where you need to backtrack are a little tiresome. Like the one where you need to get cake for the guard dude to enter into the city. However, that is a minor nitpick but it still felt a bit annoying to go a long way back and return a long back again.
Since this is just a demo (or prologue), I hope most issues I discovered will be fixed besides the game becoming more polished. Like how there seemed to be no point in finishing off defeated enemies?
Some suggestions I can think off from the top of my head that I think can improve the game would be adding a "mag counter" for weapons so I know I can reload a weapon I have in Pomu's hand. A dash counter so I can quickly know when I can dash again (albeit, that one is probably not needed-). And... that is pretty much it? More responsiveness would be nice, since I felt at times there is some lag or the game is responding as fast I wanted to. But it could be just me!
My biggest complaint though would be the lack of gore! I WANTED TO SEE MORE BLOOD AND STUFF! Like maybe blood splatters onto the floor or something when finishing or damaging enemies? Well, just a suggestion~
All in all, I look forward to seeing the complete game!
