Overall I loved the game, so.... I'l start listing the bad:
A few bugs were encountered, namely that the right side of the "item storage" is actually unaccesible and just there to trick you in believing you have more space than what you actually get (though you still have way more than you need). Also, the "leaf storm" skill says it deals low-level damage while actually dealing mid-level damage (and costing as much as any other mid-damage skill). A prompt when selling multiple object could be nice, you you don't have to reload because you sold your whole stack of elixirs mistakenly. And maybe I simply missed it when it was said, but I saw no in-game message telling you that savepoints heal, so I actually spent quite a lot of time trying to convince the innkeeper to let me sleep at the room he probably didn't even have. Also the balance could be tweaked a bit, as the summon takes waaaaay too much time to level up and when it filnally does (I won't take the time to level it over 1, sorry) it goes from 7-9 damage to 40 (maybe 20-25 lvl0 and 30-35 lvl1 would feel a bit better?) and Krat and Erion seem to fill exactly the same role (maybe on the nxt chapters their sets and skills will diversify a bit, but right now Krat is basically Erion's weaker clone, and only weaker because he doesn't have a good damage dealing skill).
On the plus side levels (though making us go all the way to 7 is a bit excessive, since you can pretty easily beat the game at 4-5... Maybe 6, so we get the 2nd skill, would be better?) actually have an impact and you feel like you progress, the story though simple and short feels like it could evolve into something interesting, the simple graphics give an oldschool feeling that's awesome and overall is a pretty solid game, without many faults and some good points. I'll be waiting eagerly for the 2nd chapter, so keep up the good work! (sorry if something is hard to understand, english isn't my main language so some of my expressions can be a bit bizarre)
