This game has many problems. The cathedral level is the best: It looks great, it has good gameplay, and I didn't notice any particularly bad bugs. The rest... you can give it a try, but prepare yourself for crudeness and bugs both in visuals and gameplay. I still found it enjoyable enough to play the entire game and to like it, but these issues were grating.

The first level actually looks pretty ugly, uglier than the other levels. But later levels get better. The most obvious visual problem that persists throughout most of the game, especially in the town areas, are the missing textures on the level borders. It's not about areas that are far away and normally unreachable, but areas that you have to visit for normal gameplay. It gives it a surrealist look, which is in bad contrast with the more realistic look of some of the levels. The construction site in particular has bad rendering problems, like parts of the crane just obviously bugging out.

A fatal problem is that the game has some possible softlocks. For example you can forget to grab a key after going through a challenge, return to the main area, and then can't get back to get the key. (This one happened to me in the Sordello Square level.) You can avoid this problem by being careful and having good savegame management. But it shouldn't happen in a released custom level. Some problems are obviously marked with warning signs in later levels, which is probably OK if you assume an experienced audience.

I didn't like much that the town squares were huge without much actual content. They were essentially huge, empty rooms. It's better on the roofs and inside. Visually, the town area also has this typical TRLE problem of using photos for textures, which make it look very odd and has a questionable effect on immersion, but it's common practice in custom levels and we're all used to it.

There are some rather odd gameplay choices, such as shooting a mirror opens a door. A lever on the back of an opened door? The bike randomly disappears or gets teleported back to Lara when changing levels. Some odd gameplay choices are just the builder's humor, like putting a bikini on a naked Lara statue. On the other hand, the game offers a lot of good gameplay besides these problems.

In summary, if you can look past some of the grating flaws, it can be an enjoyable game, with some highlights (the cathedral level) and lowlights (first level). It's definitely only for more experienced players (mostly because the possible softlocks will cause problems). The town squares may look either impressive or empty to you, or maybe both. It's probably subjective. I feel like some potential was squandered. I hope the builder continues and does away with the missing textures and perhaps tests the gameplay better to avoid softlocks.
