If you're still up for my game, and if you don't mind that it's actually an original instead of a fangame, I'd like to give you information that you'd need to complete this work.
Thanks in advance.
Edit: If yes, then I'd like you to draw right-facing portraits of the players and a left-facing portrait of the Stage 1 boss so I can have images for testing. Reference images from NTP accompany the players, but watch out for special notes.
Elssecisso Rencron / Akiyari Reiri (明槍 怜悧)
Esel Rygen / Hiroe Nikou (広江 二虹)
Note: This character wears a different outfit in EIB (sky-blue robe + straw hat)
Vija / Hasuike (蓮池)
Note: This character uses a jet pack to fly in this game, and this is not the character's real name.
Ceri (けり)
I picked it because it sounded nice; it just happened to be a word for a species of birds, and at the same time, mean "kick".
Has red hair and wears a brown robe with horizontal zigzag stripes of various colors.
Edit 2: Note that I am using an 800x600 resolution for the game. Adjust your image size accordingly.
Edit 3:
Edit 4: Since you want my progress so far, you can check the source code
here.
Edit 5: I just realized that you wanted a visual reference, so
here's one for Rygen (left) and Ceri (right). (I can, of course, draw much better than this if I do this on paper, scan the drawing, and use the line tool to trace over it, but I was kind of in a hurry.)
Edit 6: These are only the playable characters and the first boss. More info will come soon.
