Beautiful design and nice, interesting puzzles. The gameplay turned out to be more diverse than expected, although I wish some of the features were used a bit more. I'd love to see more monoclelord games in the future^^
[i]CD-ROM[/i] delivers remarkable puzzle design with a good retro aesthetic, although it's held back by a lack of quality-of-life features. The puzzles are more diverse than expected, and I haven't really seen most of these in other games. Some puzzle designs require you to go back and forth between CDs. After an hour, I decided to (1) set the game to windowed mode and take screenshots for convenience, or (2) use a guide that provides hints. It's a bit rough, but it's one of few rare cases where the term 'hidden gem' accurately describes this game.

C'est bien sympa je valide même si Sony n'approuve pas mdr
Simply amazing. Very clever puzzling, I always admire someone who can make a good puzzle beyond someone who can solve a good puzzle. This game was phenomenal. My only gripe is that it seemed front heavy, the difficulty peak was in the middle and then it got progressively easier to get the rest of the CD's. Not a real issue though, just a pacing thing, still very satisfying. I cannot help to believe that there is something more, however. The last button in the elevator is still red (i know it was clicked in the outro). And all those other rooms from the data base. Phenomenal either way. 9/10
Непогана головоломка на вечір. Такий собі імерсивний симулятор Cicada 3301 на мінімалках. Є враження, що під кінець стало простіше, аніж в першій половині гри, але все одно все сподобалось. А насамперед є демка. Спробуйте її, і якщо зайде, то беріть, бо в цілому вся гра в схожому спектрі.
This is a fantastic example of old abstract puzzle games. It is most reminiscent of such browser based ones as notpron but within a nostalgia and purpose-driven shell. The vehicle/shell is well-designed in that it has explicitly all the tools you require to solve the puzzles within. That is an important aspect as you should not need to search the internet or outside sources unless you are told to. A love letter to classic abstract puzzle games. *There's a couple bugs I ran into later on that caused rather unimportant soft locks (you just relaunch just as well). You will not lose progress. I would like to see more from this developer, a lot more in the future.
Varied puzzles, clever design, captivating aesthetic.
A short sweet review for a short sweet puzzle game. Defo enjoyed this one. The puzzles aren't too taxing but are enough to get you thinking. Loved the retro CD-Rom style and the game gets you switching up the discs regularly for previous item. Was FUN 8/10
A really fun and satisfying puzzle!
Great!
