I like the premise, but a bunch of things are not very clear. For starters, what the upgrades do. Likewise where we need to click (I figured it out fairly early but still notable). I also did not hear any VO lines. No "Andre" or "Umeko" or anyone. Also the map in the corner is rather hard to read and your progress is not at all clear, and it seems like the game crashes with an error (or at least cryptic partially coded text) at the end. Finally, after upgrading the coin button enough it becomes very hard to see the prices for it; it might be useful to move the buttons slightly to the side.
I admire the effort, and I hope this game and your future efforts flower.
