This is a good conversion, but playing it, I have noticed some problems with the high score table. It seems to get confused after the first score. Then the "real" value of your score doesn't get entered into the table and it corrupts over time. (WinUAE, A1200 4Mb RAM)
Once again a very nice and clean arcade conversion. Our German-language review can be found in our recorded livestream starting at 02:44:17. English subtitles are also available. Subscription to our YouTube and Twitch channel is welcome. 🙂
Great new arcade game version. I've also added it to my new video along with other recently released games. Hope you like it.
Hey there, I hope you don't mind, but I popped gameplay footage of your game into my latest
August 2025 "new games for retro platforms" video. Many thanks for the game.
hardware sprites with 5 colours?? how is that possible
4 attached sprites for cops, using 16 colors. Rest is blitter.
Awesome!
