Thank you very much for the review. I'm glad that you mostly enjoyed my game. To address a few of your points:
I felt that an "anytime you want" dash option made combat too easy unless I made the monsters faster as well which made combat way too hectic. I know that disabling dash is a big no-no to many but the game just played better without it, in my opinion. Maybe a temporary dash with a stamina bar would be a good addition. I do wish RPG Maker gave us more control over the speed of characters and events.
The pixel movement does indeed make lining up your shot a little more challenging. I did my best to compensate for that. Later on, you can get a weapon upgrade that makes it super easy to hit everything as its hit radius is much wider.
Rescuing souls is your primary source of money in the game. In the first area, yeah you only get 2 per rescued soul and 1 if an enemy drops a crystal. These numbers double each time you advance to a new area so if you want to acquire the cash for all of the weapon and armor upgrades, you'll want to do this. If not then you can charge straight through but you'll have a harder time.
I know that the natural inclination for most RPG Maker games is to stick your hands in every crack and crevice in hopes of getting hidden loot. That it how many game utilize these cave features. The reason you see so many of these in Eremiel is because they are spawn point indicators. You generally want to keep a relatively safe distance from these as a monster could pop out of one at any time (unless you're standing right on it, I'm not that mean).
I likely won't do too much more to this title besides polish up a few things that I didn't get a chance to before the deadline. The scope of this game was set to 1 hour. The story, game play and level design was all crafted around this desired play time. I may use the knowledge that I acquired from this project to design a different, much larger game in the future, though.
Again, thank you for playing and for all of your valuable input. I believe that I have your game downloaded and will give it a shot as soon as I am able.
