Thanks for the suggestions.
- Staircases: they're on a fixed grid (see screenshot at bottom) - it's fixed as 16x16 pixels that the Amiga blitter works. I may ask Earok for suggestions there as he does the engine but meanwhile I suggest you simply press up before at same time you're moving towards the stair: when Simon reaches the spot he'll automatically snap to the ladder (that works on all Castlevania games, all them have fiddly spots, possibly because it's grid based too and even worst, some are 8x8 grid, so we're good here at 16x16).
- I know of that sewer issue, I might get to redesign this specific stair position or (an idea) is to eliminate its tiles (collision with player) after Simon leaves it, so the stair didn't get in the way anymore (and there is no backtracking in Castlevania anyway).
- Violet/blue colors in the upper part of the waterfall: that's the background parallax from the mansion window displayed behind, even after I issued the command to get rid of it as soon as player enters this area (it didn't obey). On a different version of the engine it works. It's hit or miss, sometimes it works on this version of the engine too. Bear in mind that Scorpion is an experimental engine and ongoing project and these minor issues are to be expected, realistically, even at the final version of the game. Because this game will be finished but the engine development will continue.
- Hits: on a modern game you do raycast to get a direction but that is not the case on a 30+ years old hardware such as the Amiga, so, the most efficient solution was to simply check the side that Simon was facing.
