Hi,
I decided to play this and, at the same time, to download the 210 levels of terror for TSS and GatEB and have a look. I will start with a general and more comprehensive comment, which is about your “210 saga”. I think the concept is good, and the puzzles are fun so far, and beginners/new players friendly.
However, if I were a beginner, I would choose only one of your “210” hold to start with, particularly, TSS one, since it is the most complete in terms of the elements used. Once I complete it, I am not a beginner anymore, so there is no point for me to play again another “210” hold, despite being medium difficulty once you reach certain levels.
Now, here’s my point: since every level is pretty small, have you considered joining every level 1, every level 2 (and so on) from the TCB, GatEB, and TSS into one single level, maybe even by making “separate” parts of the level to reflect the game style (lights, weather, room style, layout etc.)? This way you would have a single hold with every level being around 9-10 rooms, all of them of the same difficulty (btw, level 2, going down, is the same for TSS and GatEB for now). This concept could be applied to AE and JTRH holds, but I do not know how they are or how far you are into those. Please note that this is just my opinion and what I would do, but I think many players will get bored or do not play at all 5 different holds with the same concept. However, one (or two?) hold combined with the same concept and puzzles, I would definitely play that, especially because the puzzles so far are fun.
In addition, you could add some easy challenges for the first levels, which could intrigue new players, such as “clear the room facing only E” or “don’t do that” and stuff like that.
That being said, here’s some general and specific comments for the first 8 levels of “210” TSS, see also demos attached.

× Overall, the aesthetics are pretty poor, and even though it is a secondary aspect, I think it would be good to polish it a bit. For instance, placing some decorations, placing some pits, water, stuff like that, to sugarcoat the level.
Going down: if this is supposed to be an introduction, 1S1W is not trivial for a new player or as a second room.
Not too hard: 1W, I liked this room. 1N1W, also good room.
Don’t get shot: good easy puzzles, aside from 1S1W, which is cool but harder compared to the other rooms.
Branched path: 1S1W, I liked this one a lot.
Stop and go: best level so far. However, if what I did in 1S1W is intended, this is not easy at all.
