Está muy mal que acabo de descubrir esto después de 6 años. Es lo más bonito que me han dedicado <3

As much as I like oldschool trance, you could have worked a bit more on this. Like it's not bad that the song uses 5 overused presets but the entire song is that arp score from z3ta+ for 5 minutes. Transitions and filtering helps keeping this interesting but melodic variation is minimal for a 5 minutes long track: All synths plays the same score.
Maybe all this can be resumed in just my problem that knowing almost every sound from 2000's hands up music, now doesn't feel the same when you know the 'magic' behind them. But I guarantee adding at least one more score that follows the progression with different rhythm will make a difference for a track whose purpose is just an arp preset.
Anyway, if you enjoy it as I did back then, that's cool hermano. I wish I could've sounded like this when I started with techno.

Saw this at the review to review thread. The hi-hats could be a pair of dBs louder, as well as the general volume of the song.
Anyway, the synths are ok for a videogame theme, I liked a lot your use of the slide/porta tool, but I suggest adding some chorus or detune to the chords for more wide sound.
About sidechain, it is also good, not too long not too short, there are many methods to do sidechain but I didn't understand what you mean with fake saw ADSR envelope. I guess you talk about sidechain with an envelope controller and linking a bunch of gain parameters to it.
About the score itself, not sure if on the description you talk about a 'prompt' you used as one from an AI music generator which let me tell you, if that's the case, your melody would be based on something you didn't make, even if you cast it away and decide to change the style or just some notes. That's a big no for me in terms of originality :\
Keep learning more tricks, there's a lot of cool things. And remember to not rely on prompted music, that won't make your scores interesting.
