Thank you for your feedback. I recently tested the game on Catouche Flash, and it worked perfectly. However, I appreciate your comment and will keep it in mind. Thank you.
Redownloaded and now there is a splash screen, startup menu and level select. Weird... the previous download was a demo(?) where the first level I had to immediately climb. Still quite severe slowdowns on BGB emulator
Yes, the previous version was uploaded by mistake, but everything is fixed now.The slowdowns are indeed an issue on emulators. However, the game runs well on real hardware using a flash cartridge.
