Thank you, I'm glad to hear that you picked it up again and made more progress.
I see what you are talking about with level 2. It is tricky and requires some fast reactions, but if the game is running correctly with no bugs/glitches, then the barrels at the top should always be visible before going on the ladder to the last camera position. It'll take quick jumping, but following the patterns/timing of the barrels will help.
The combination of the barrels and the jackhammer on level 3 seem to be overloading the GBC and cause scripts to stop running (I don't know the technical side behind it, all I know is that asking the system to do all of that causes glitches later on that are unrelated to scripted events). So I'm considering removing it in the next version update and perhaps making some of that a bit easier as well. Congratulations though on making it that far, level 3 is certainly the hardest!
Also, GBC colors are (in my experience) wildly varied depending on how it's emulated/what the display is. For example, a factory-original GBC screen is much less vivid in color compared to my IPS-backlit modded GBC which seems to display a greater saturation. Additionally, an emulator like bgb on Windows has a lighter color display than OpenEmu on Mac OS.
Yeah I agree completely, indeed quick jumping is necessary at that part.
About the jackhammer, maybe the scene overloads bc the scene itself is filled with scripts. Ofc I don't know what causes it, but maybe you should consider testing this in a "blank" scene w only the jackhammer and the barrels to see if it's really this mix that causes bugs.
And yo I didn't knew that different gbc models displayed different color shades, guess from now on, I'll only play these games at the emulator. If there is one thing I love in a game, is very saturated colors.
And yeah I guess that's basically it, thanks for the talk, keep making games, and at the meantime I'm awaiting your video
