Here's another little flaw:

If you go here, where i put the arrow, because of the way the game is made you'll end up in the next tile. Not only is it annoying, but (if you know how) you can still control Juni when this happens, so you could just move around the guy's house and not get the umbrella. I'm not sure why you would want to do that though. The problem can be fixed by removing this particular tile (the one i circled).

The first few screens look really good but you've got some of the major design-flaws common to most first-time levels; piling in loads of enemies to artificially hike the difficulty and then mislabelling the level's difficulty aswell.

As-is, the first screen to the left is Hard and so off-putting just to look at at 2am that I've lost the will to continue playing tonight. I'll try to get back to it tomorrow so I can offer more feedback.
