Ok there are a few things that I think could be done, I hope it isn't too late to change anything since you've already released your game.
First and foremost, please stop making my web browser open a new page everytime something exciting happens, being constantly reminded that this is a demo and I need to pay for the full game is actually kinda irritating. This is something that should only be done at the start and end of the demo
There is a kid jumping a skipping rope in the town and when I speak to him form the left he quickly faces me and turns back down, you should put a 'Direction FIX' on him to get the desired effect of being ignored
Scratch that, quite a few people here seem to be doing this actually.
This battle music is awesome, I'm really
to it, I wish I could say the same for your town music though, the default RTP is not really my style.
Seriously this is the 5th time those snakes have defeated me ;_;
Ok so I've been playing for around half an hour, once you level up enough, those snakes aren't a problem anymore. But holy crap man, leveled up by only a couple of levels and I already got a shitload of new skills to use.
I like your battle music and the gauges that you use to determine the attack order.
I also like that you have a display in the bottom left corner which shows your characters stats.
The animations that your character has are also brilliant, I love them, and those other characters that I've never seen in any other game are also nice to see.
As a suggestion about your puzzles. Be wary of how you implement them, the question of 'which coloured slime is the strongest' is subject to what I actually think.
Because in my own game, a red slime is not the strongest coloured slime. So your questions should be common knowledge in your game.
Also, you have far too many random monster encounters in your game, reduce the step counts a little bit, please.
I didn't do much else, but from what I've seen so far, I think this game is pretty good for only $5.00
As for the story itself, you are correct, I've literally found absolutely no story to this so far, and story plays a big part in a game for me.
So in my own opinion, this game seems to be worth $5.00
But I recommend everyone to try the demo before deciding.
