I am not one who usually writes comments on games, but after multiple runs, I just had to share what I love about and the experiences I had with 10-103: Null Kelvin.
The gameplay change is drastic, from 10-103's slow pace, closer to the survival horror genre, to a faster, action-y style.
While some might not like the change in gameplay, I personally am addicted to it. I have no idea why, but run after run I did not grow tired of rolling under UT's deadly hug or under a necrotic's chest-spear thingy.
what I loved the most about the first 10-103 was its world: not much was told by the chatter between Specter 8 and Morpho, but by the environment. Null Kelvin is a huge leap forward. Its lore has enlarged massively and is starting to become really intriguing (more intriguing than SCP's in my really personal and biased opinion), with some really missable quips, such as the Specimen 19's description before and after opening the shutters.
After multiple completed runs, I still manage to find such quips; In a recent run, during the boss fight against the UT with the flares, I noticed the faint logo of Aegis with "Forward Containment Base" on it where the Osmosis Legion logo stood.
The environment itself is a huge step forward from its predecessor: It just looks better. I had some FPS issues on fullscreen during the outside scenes, but it's probably because of my shitty setup.
10-103 is the name of the game, and damn if those 10-103 were something. The different types of necrotic go hand in hand with the shift on the more action style of gameplay. It's a shame that Specimen 15's behavior wasn't expanded further, as I really liked the idea of a fast enemy who you had to constantly dodge.
Overall, 10-103: Null Kelvin is a huge step forward from its predecessor, and overall one of the best experiences I ever had on Itch.io. I'll assiduously wait for any new game from Nerdspartan.
p.s. real shame there's no discord server on this afaik.
