Said I'd make sure I tried this out and man I'm glad I did!
The gameplay is great, a nice mix of rock paper scissors and minesweeper. Though I admit I played in a very boring way for a good chunk of the game because I just kept right clicking everywhere and slowly grinded my way up the first couple keys lol. But once I got to the green keys I started actually engaging with it more and it was really fun! Especially nice clearing out all the enemies after I got the true key and beating the game.
The graphics are beautiful pixel art, combined with the emails (I'm so happy Kokoro and I got in as spam accounts btw) it really gave off the hacker vibe! And the emails were pretty well written and I love how they evolved as you progress.
As for the audio I think it fit quite well, but due to my mixture of boring playstyle at the start plus the constant clicking did lead me to eventually just turn off the audio and play YouTube in the background. But I fully appreciate any jam game that has actual settings, and quite frankly I end up turning off music in most games after I think I've heard it all.
The tutorial I think was a great addition, though I'm not sure if I missed something at the start but at first I thought you had to have that square crosshair over things to interact rather than just the cursor. I did figure it out within the tutorial, but from my own experimentation rather than being informerd through the tutorial. But that being said, part of a tutorials purpose in my opinion is to allow experimentation with mechanics, so it definitely nailed that aspect.
Also its really cool that you got to make a sequel to a previous SBIG entry you made! It actually seems to be something of a common theme this year lol. I got to do it partially once with my game last year, and even certain parts of Thesmothete, but no proper sequel/reboot. I haven't played the original but from what you posted in discord you've really come a long way!
Excellent work!
