The online leaderboard is real and it has two factions, which is the best version of this I've seen in the jam. Two columns side by side, NETRUNNER in blue and CORPO in red, with actual players in them. For a high score chaser jam that's exactly right, and having the factions compete against each other is better still.
The main menu is polished, a synthwave landscape with a red grid and a NETRUNNER STATS panel showing best infiltration, total runs and your faction. It treats you as a persistent character rather than a loose session, and being greeted with "SYS_ADMIN, WELCOME BACK" is a small thing that lands. The micro challenges are varied and on theme, each with the rule written on screen: "RULE: CONNECT TO PORT 8080", "RULE: CLICK IN ASCENDING ORDER", "RULE: INJECT PAYLOAD IN SAFE ZONE". Each takes seconds and all of them fit the hacker fantasy. The TRACE bar filling in green while you work is a great source of tension, and the red skull in the corner says the rest.
Honest caveat on my results: I did 5 runs and finished all of them on 0. The TRACE bar fills very fast for me and I'd hit 100% before completing a challenge. A good chunk of that is on my end rather than yours, so take the difficulty note with salt. Still, the suggestion stands: the first two or three challenges could have a slower trace so there's time to READ the rule. My first run was lost purely to reading "CONNECT TO PORT 8080" and looking for which one it was.
Two small ones. Retry on the end screen only worked with a double click. And the nickname warning says you can't change it later, which is good, but it's worth also saying that it goes onto a shared public leaderboard. I only knew that for sure once I saw the board.
Of the games I failed to score in, this is the one I blame least. Good structure, and the faction board is a great idea.
