SMEE VNs tend to be a bit of a pain to read unless you have a fairly high tolerance for insufferable MCs. Their MCs tend to have the emotional and mental maturity of a hyperactive 12 year old boy, only increasing slightly to that of a mid-to-late teenager once you enter the heroine-specific routes - this can be humorous at times, but tends to feel forced most of the time (ie. "HARHAR, LOOK AT THIS FUNNY SHIT I JUST SAID", in extra large font, complete with smash sound effect and screen shake - basically the same idea as using a laugh track to try and make people laugh at specific moments). That said, Making * Lovers' MC is probably the most tolerable of all the SMEE VNs I've read (the others being HaremKingdom, Fureraba, and Sugar*Style). MC still tends to make stupid decisions and spout ridiculous/cringey shit, but with less intensity and frequency, while still retaining the humor. That said, if you absolutely can't stand SMEE VN MCs, then you will still likely find this hard to read at times (some of the worst of it was during the early parts of Saki's route for me).
Making * Lovers uses ladder-style branching choices, which split off very early compared to most other non-kinetic VNs - it has a very short "common route". The routes are highly concentrated on the chosen heroine and a few side characters, with most other heroines not even appearing again (or at all) after a route is locked in (eg. you can complete all other routes without even encountering Saki). This has upsides and downsides - the upside is it really digs quickly into each heroine's story and personality, whereas the downside is that there isn't a recurring friend group that gets well developed prior to locking in the chosen heroine. Without such a friend group, things like reactions to the relationship or various events are left to the less-developed side characters. These factors lead to Making * Lovers feeling more like 5 single-heroine VNs wrapped into a bundle, rather than one VN with 5 heroines.
The heroines are quite well written - better than most moege I've read. I would say most of them are equal or better than the "best" heroines from SMEE's other VNs. My personal route preference is Karen > Reina > Saki > Ako > Mashiro. I think Mashiro and Reina in particular would be a bit divisive among readers - both are quirky, but in different ways. Reina is quirky in an annoying/obnoxious way at first, but she gets a lot better as she opens up to MC. Mashiro on the other hand is quirky in a kind of cute/eccentric way at first, but to me her behaviors and mannerisms grew stale pretty quickly.
The art is great, and the music is about average as far as Japanese VNs go - nothing much to say or complain about here. The character designs are all unique and cute. H-scenes are pretty much standard for Japanese VNs, and there are no animations aside from character models blinking.
Overall, Making * Lovers is my favorite SMEE VN by a large margin, and among the better moeges I've read in general.
