AVEE'S PROFILE

I think it's all about the border between challenge and frustration.
Primo, since the rooms are randomly generated, none should require a particular upgrade to pass (for instance, a huge gap requiring rush jet would mean game over if you didn't get the room it is found into).
Secundo, if we have to start all over at room 1 when lives are exhausted, it would be less frustrating to be allowed two more tries at the room we died into. So that's a vote for 3 lives.

Looks good to me.
I don't know if I'll be able to explain this right but the base of brick walls don't match with their corners... Adding a small (about 16x4 pixels) wall portion below the corners and lowering the dark area of the base by as much would look better.

In terms of level design, it seems a bit confusing to me because there aren't any tiles or objects used to mark a path.
Aside from that it looks pretty good. Maybe a bit of deeper water in the eastern pond would add a nice touch.

It's always a pleasure to answer such questions!

A) Shame on me, I forgot about foes' immunities. I honestly don't know if I will add immunities because I already programmed weaknesses (twice the damage from charged shots). I'll think about it. Thanks for pointing that out.

As for your other questions, they have mostly been answered already. Just take a look at the previous posts and Images section.

B) There will be additions to the original game such as new dungeons and enemies. The global storyline is the same yet I will edit many things. For instance all the main characters are more developed (check the Characters section for more information).

C) That information will remain confidential for now :P (basically, that means yes...)

D) Take a look at the Images section. I already ripped and edited the wyrm from the Windmill Cave and the caterpillar and fly from the Swamps. Other enemies and bosses will be ripped from the original game (expect a certain giant insect coming up soon) while some are completely original, such as the Recon Rat in Velyagun's Great Wall.

I hope you'll enjoy the demo (coming soon). Thank you for your comments :)

A big disappointment implies high expectations. However I never had such expectations for an RM game... Still, I'd say Eyes Without A Face was pretty disappointing because of its length, unexplained plot and the amount of overly positive feedback it has.

Regarding professionnal games, I'd say Wild Arms Alter Code F. It's a remake of an awesome game, but they managed to make it as crappy as AVGN's worst games.
