Ok, about monster-capture:
-At the beginning I only captured monsters once in a while for the rewards.. in mid game a lot of monsters were not captureable (undeads, demons etc.), but the scan didn't say so and suggested food for the capture which didn't work. This happend in 3 or 4 areas. In the endgame I captured monsters again, because it varied the battles a bit.
Very Good:
-The Beginning: Epochs decision to finally do what he wants is a common dream of every person today - the plot telling which leads to this developement is very well done. The mother which drags her children inside the houses to save them from epochs crew for example, that creates a very creepy atmosphere.
-Marcellus: Arrogant, manipulation, the sucessor of all evil stereotypes.
-Slade, the drunken master, Lee, Elijir, Elise all have very very well done - I even like the king

.
-The mansion: A really great idea to tell the player things about the past. And demon hunting is always cool

-The riddles: Not too hard, not too easy. Well done.
-money balancing was very well done thoughout the game (very rare in rpg-maker games) till perhaps the Drunken master appeared. After that I could swim in gold, the monsters just dropped so much.
Bad:
-The hooded man, I suspect him to be a crystal guardian btw. - well he just is a big idiot. Dialogue in the beginning, Marcellus: "Let's not draw to much attention".. the hooded man then goes of and kills like 2 dozens of elite dragon guards which chase after epoch, how is that NOT gonna draw a hell of attention?! He watched the crew like an idiot and he screwed up again shortly after with the biorobot - if he would have done his job properly and watched out for the chasing forces, he would have noticed....
-Elizabeth: The Spoiled princess tomboy character is just sooo overused. And the Epoch-plot around her is just weird. At the beginning Epoch mentions her only one time! (- or his buddy Cloude: "Do you still think about Liz?") - 5-6 hours later he's going far too crazy around her, it's like his character has changed all of a sudden.
And what the hell is her outgoing and bright attitude - I think it's a bit exaggerated.
-The balancing with those scout bosses, altough weaker at the end - the first ones were actually damn hard. Oh dear, I used up all my items too beat the first one in the forest with the lake (the one with slade bleeding), and later I got a second very very hard lvl2 hidden monster. Oh my god what beasts.
-Upgrade Coupons: Easlily missed, I only found around 4 or 5, nasty to look out for white birds during gameplay.
All in all you have my respect for always introducing new features during gameplay. This somehow keeps everything fresh. Good job
