The obvious out of the way: it's hard to say anything conclusive about a straightforward prologue for a larger story. What's there certainly feels appropriately prologue-ish, with the pace never slowing down from the effective in media res opening and the world remaining sparsely enough sketched despite the numerous pieces of lore & backstory. If there's something that feels extraneous at this point, it may be establishing the antagonist(s) as individual characters; the conflict would feel clear even if it was just Mikhail versus a bunch of nameless troops, and the main baddie being around doesn't really pay off yet.

As for the prose, it's generally pleasant to read – good variation in sentence structure, the flowery similes mostly work – but not without errors. Most notably, the tense changes all the time, and there are plenty of punctuation and grammar mistakes as well. Though the clarity of what's happening in the story is only threatened near the abstract ending, I think some editing would improve things a lot; many lines lose their impact due to wonky grammar.

Visually, the only real weak point is the lack of shading making the sprites look more cartoony than what would feel right, given the tone and genre. The sound design is good, though, even if the magic SFX feels maybe kind of... digital, for a lack of better word? Like computer sound effects? There just isn't that much physicality to it, which clashes with what the story is depicting. All in all, an unpolished but functional start.
