A truly stunning game that I thoroughly enjoyed! RETREAM stands for quality. I created my longplay with the help of save states (otherwise you might think I'm the best gamer in the world).
Thank you so much for the information and the compliments!
When I returned to the C64 quite some years ago, one of my objectives was to make colorful hires games, so I chose ECBM for the platform part of the first QUOD INIT EXIT (the sky, instead, is a hires bitmap). In this game, I "just" pushed things further ;)
By the way, I'm not a C64 historian, but I'm under the impression (and I stress that it's an impression, so I might well be wrong) that after the release of the first QUOD INIT EXIT the ECBM got more love than before by the C64 scene.
