Good evening! Good news: I've just tested the latest version and actually, for the first time, it hasn't crashed. I tested it twice and was able to play through the 5th world without any problems. The only things I noticed compared to the official download version were the jumping red skeletons which seems to be a lot more aggressive (wildly jumping around). Furthermore, the main character's whip is also used simultaneously when using the secondary weapon, which was not the case before. I don't know if that's intentional? The screen also takes significantly longer to load when starting a new game or after level warping (around 2 seconds) because the image is "stuck" for a moment. Otherwise, I haven't noticed anything negative, even though I've only tested the 5th world up to the beginning of the 6th. By the way, the "Scorpion Engine" is still displayed when the game loads. Please let me know if you need further tests and feedback. 🙂
Excellent news, thanks!
Each time I change the Scorpion Engine version, it may add those little glitches that you described. I have a text file list here on my computer with many, which are accumulating. Not actually the engine's fault, that's the nature of game development in general, it's hard and unpredictable. Even more on retro hardware. Also, that's why the majority of Amiga ambitious game projects may never be finished: the motivation wears off as the problems tend only to accumulate towards the project's end!
But, on a lighter note, after this good news, I can see the light at the end of the tunnel. Crashing like that on world 5 was a serious issue that would harm severely the project, while minor issues here and there are to be kind of expected due to the experimental nature (as an ongoing project) of the Scorpion Engine.
