Hey
GaBoTiCo I gave it a quick try with Leo.
Here is my feedback:
PROS
- The graphics are nice. Its a fresh paint over the original sprites and they look different from MersoX's game, so it looks unique.
- The game looks fluid, fast paced (more than the NES version, which is good)
- The intro is very cool. And thanks for promoting the engine and the forum

- I loved the musics
- I liked that you had split the background of the first stage (the area in flames which appears inside the elevator). It gives the stage more depth feeling.
- Nice use of subtle transparency on the ground fire
- The scenes (inside the game) are pretty cool
WHAT I THINK IT COULD BE BETTER
- Leo's first attack is kinda slow, while all other attacks are fast. This affects the gameplay a bit.
- I would give the characters a SELECTED animation. You can use one of the attack frames for that, and maybe even add the COWABUNGA sample when they get selected

- I saw that you used direction BOTH on the stage. I think direction RIGHT would fit the game more, but if you want to make the stage to scroll both directions, you need to include a BLOCKADE, to avoid player traveling back all the stage
This is how I set on my stage:
wait
at 1323
#--BLOCKADE-->
blockade 1423
at 1323
I use the same value on "at" and I add 100px in the blockade value
- I've discovered, by accident, that Leo has a special move. Maybe it would be good to include a movelist, even in txt form.
- Rocksteady attacks are fast (like they are on the arcade), but the recover of those attacks is a tad too fast - specially for a first boss.
This is something common in some OpenBOR games, but try to remind this triad - POWER, SPEED, RECOVER. You can always have 2 of them, but not all 3. At least not for the first boss.
Edit: I've made a diagram for there here http://www.chronocrash.com/forum/index.php?topic=5368.0
Keep the good work, it has a lot of potential.
