Being a fan of old school games, especially 8-bit, this title brings back a lot of good memories
Just played through the first few levels. Very nice retro feeling, didn't find any bugs.
You may want to consider adding a longer transition between levels or after death.
Many words that are written together in German must be separated in English, like MOUSEFUNCTIONS, MOUSEBUTTON, HIGHSCORELIST, GAMESTART etc.
On the LITTLE HELP screen when starting the first game, MUSIK should be spelled MUSIC and there is a typo in RELEASES ( REALESES ).
I love the music track and the raster bars
Thanks for the trip down memory lane
