This game wasn't on my initial list since it looked to be way too retro for me, but given that you returned me the favour first and that I just happened to have a 90 minutes-long train journey, I decided to give it a go and try to find out who is actually hiding behind AnonymousSilverDazeDev.
There is actually quite a lot to say about this game.
This is the story of RanomPokemonPlayer who learns that Girlfriend is going to the university far away from here in a month. After losing his thoughts in a video game session, he got himself isekai in a strange world with his friend Gyro in a world looking a lot like the real world. Is Girlfriend around there, and if yes, will they be able to save her in time?
I'm kind of conflicted on the battle system: it is quite nice from the point of view of the player with the handling of the MP gauge. On the other side of the coin, this system doesn't work well for the enemies. Most of them can only perform a single action and then have to use their MP-recovering moves. Moves that seem up to now to be nothing more than a simple guard. It is especially a problem for enemy whose first action is a self-buff that will disappear quickly given how buff work in this game, and for bosses that lose multiple turns due to that mechanic. I won't pretend to know to deal with that, but I may suggest trying replacing the enemy guard by a simple attack move that also restore MP, so it doesn't seem they are losing their time.
This game has a really high encounter rate, but it kind of make sense here, firstly because HP and MP are fully healed for free between fights, secondly the battles are quite short and thirdly because the player need those cards to progress the gameplay. Running away seems to never fail also. Backtracking would be the only case where such an encounter rate would be a problem, so I hope there will be a no-encounter card or music at some point.
Buff skills seem currently to be overpriced to be useful, and the scoring system based on speed doesn't encourage their usage.
Graphics were what I expected: very retro-looking so not for me. I'm sure there are other people that would love them. Two points I noted in that department:
-Characters seem to have always the same face during dialogues. More emotions would be nice.
-Up to now, there isn't much exploration in this game. Maps seems to have only encounters and obvious treasure boxes. I mean, there isn't much things like intersections, secret treasures or interactive elements who aren't doors. I hope it changes later.
I liked some of the musics way more that I expected, especially since if I'm not at all in 8/16 bits musics. My favourite was probably Zeta Squadron. If I'm not mistaken you actually made the music yourself, so well done. One problem in the sound department for me was the SE: they sounded way too loud compared to the quieter bgm, especially the ok one. It is the most obvious in the music gallery. I would heavily suggest adapting those.
Random remarks:
-Kani's attack debuff seems not working against her boss (at least, there wasn't any icon above it), and there was no feedback concerning the failure.
-Restore seem like a weird skill name for a mp-recovery move. It stringly suggests it is a healing skill instead.
-Equipping twice Motivate increases its cost for some reason (not that it matters, but still).
-It is quite funny to me that healing spells with power 20 and 40 seem to be healing exactly 10 and 20 hp.
-The description of the skill Sword goes outside of its message box
-A random passability bug: 
I don't know if I will have the occasion to come back to it, as there are other long games I already promised to play more.
In the end, I give this game a "No fairy in a rpg maker MV game? This is intolerable!" out of 10.
Concerning the 'find the anonymous dev mystery': it was actually pretty easy and quick to unmask you once I got access to the internet despite the fact I didn't even know about you before. 🧚🧚🧚
