Yes that is good!! The exact replica of the game on Amiga!!! This game is aimed more at the nostalgic of the original version of the 90 years, than a contemporary player. the lag game sometimes, but not really gene, and we quickly find the sensations of the original version!!!! Of course it lacks all the same keyboard for playability... I no longer count the sleepless nights spent on this game on my good Amiga 500 being teen!! and I don't think I'm going to count my hours on it either. A player who waits only for the last Opus.
