The concept of OISC is not new to me; in fact, having recently played "A=B", I've seen how far to the extreme it can be taken (in that case, only assignments were used). So, at least in this aspect, the game only surprised me to a certain extent, even though subleq is a very fun and expressive "language." What really amazed me is that this is the first assembly programming game where there is actually a (virtual) RAM. Usually, in this genre, you're limited to working with a series of registers, or at most, in some levels, they implement an array/stack/queue that acts as a data collection, but it's always something external to the language's architecture. Here, instead, you have 255 bytes to work with, and above all, when you compile the code, it gets allocated in the RAM alongside the data. And this is normal because instructions and data are virtually identical; it's only the logic of the program that allows us to distinguish them, but we tend to forget this, made lazy by high-level languages. It is fascinating that you can therefore write instructions that go write into the bytes of other instructions—self-modifying/self-generating code. And it's not a secondary trick for crazy…

This is the programing equivalent of smashing a rock against a wall over and over again and hoping the shards make a fortress and I love it, 10/10

если ваша молодость была безвозвратно испорчена изучением ЭВМ, эта игра определенно для вас, а еще заменяет сеанс психотерапевта👍👍👍👍 (без шуток, максимально искренне и честно - это лучшая игра, которую я видел в своей жизни "всем рекомендую")

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.

Games like Titanfall 2, for the pilot or for the Titan

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.
