Moving backwards and erasing all traces over a bridge automatically forces that data back to memory. #indiegames #gamedev #indiedev #puzzlegame14 Sep 2025 11:16 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lys63s7mdc2rhttps://bsky.app/profile/jefrsilva.bsky.social/post/3lyq5o6lnx22bWhat if the hacking minigame was the entire game? #screenshotsaturday #indiegames #indiedev13 Sep 2025 16:03 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lyq5o6lnx22bhttps://bsky.app/profile/jefrsilva.bsky.social/post/3lypubwfpps2tTunnels let you jump horizontally or vertically to any node of the same color, allowing you to move faster and access areas of the server that were previously inaccessible. #indiegames #indiedev #gamedev13 Sep 2025 13:15 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lypubwfpps2thttps://bsky.app/profile/jefrsilva.bsky.social/post/3lyo4bwjkvs2mFirewalls (diamond-shaped) block download attempts if your route passes through them and prevent passage if your memory contains a node of the same color. This often forces you to find alternative paths, sometimes leaving you exposed to sentinels. #indiegames #gaming #puzzlegame12 Sep 2025 20:33 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lyo4bwjkvs2mhttps://bsky.app/profile/jefrsilva.bsky.social/post/3lyndkhxbq22pYou can use the stack memory to store colored square nodes and write them into empty square nodes. As the name suggests, the memory works as a stack, so the last node you add will be the first one to come out when you need to rewrite a node. #indiegame #gamedev #puzzlegame12 Sep 2025 13:10 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lyndkhxbq22phttps://bsky.app/profile/jefrsilva.bsky.social/post/3lylgpsezjc27A gate with a number in it will only open if you choose a route that contains exactly that amount of matching color nodes. The route profile helps you keep track of nodes in your current route. #indiegame #gamedev #puzzlegame11 Sep 2025 19:01 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lylgpsezjc27https://bsky.app/profile/jefrsilva.bsky.social/post/3lyj6teum7k2zAchieve a ghost run by hacking a server without being detected.

Installing backdoors may enable different attack routes less exposed to detection. You can also erase your traces by moving backwards along your path. #gamedev #puzzlegame #indiedev10 Sep 2025 11:55 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lyi6ha76jk2shttps://bsky.app/profile/jefrsilva.bsky.social/post/3lygxhp62us2sEvery run begins by selecting a server to hack. Once connected, your objective is to download data from all databases and then disconnect without being detected. After your first move inside a server, you have 20 secs before you are traced and eliminated. #indiegame #indiedev #gamedev10 Sep 2025 00:18 +0000at://did:plc:inm5cax4sbpd6u574xcppd6d/app.bsky.feed.post/3lygxhp62us2shttps://bsky.app/profile/jefrsilva.bsky.social/post/3lyfspp6was2aEvery defense has a flaw.
