Hi all,
I bought construct2 and improved game in the meantime.
You can download it at the address: host9.office.crystalvision.pl/scrap-win32.zip.
I exported it as standalone app, to avoid all different browser issues.
Although, there is still much to do. I need to create menu UI, because it's just mockup right now. There are also some sounds to do, some backgrounds and more assets for environment. I also plan to create introduction at the beginning of level, that will explain all new gameplay features.
