RPGM games usually play in the same way. The good ones manage to make several additions in terms of content, gameplay changes, crafting, location variety, enemies and gameplay mechanics that transform the experience from a turgid RPGM affair to one that is highly enjoyable. This one does try to do similarly, but it also subtracts a few things and goes far in one direction for the game to get beyond the "average". My biggest complaints here are regarding the interminable fuckfest that happens after a loss and a very small amount of content.
So Lisa's Macguffin plays like most RPGM games. There are unique things about it - for example, you're better off sneaking around instead of engaging enemies because they will utterly plow you if you give them a chance. This weakness in the heroine is mitigated by the reliance on items - which is unique for an RPGM game. You can craft tonnes of knick-knacks and crafty doo-dads that help you defeat enemies in a jiffy, but the crafting materials are rare so the smart play is to avoid enemies and use these items carefully. However, when you create a game where the obvious choice is to avoid enemies, you can't just create tanky damage-sponge bosses because that's what Lisa ends up facing. It means all your skulking was for naught and you were better off trying to fight through enemies anyway? What an awkward design choice. This is further exacerbated by the fact that if you lose, you are fucked for 10-15 turns before being given the option to surrender. I tried long-pressing surrender but it just wouldn't work. And it's a chore to go through the same scenes again and again.
Nonetheless, there are other interesting mechanics. I've already touched upon crafting which I always enjoy but you also have the ability to find and plant seeds which then grow into some relevant items. The game does give you money but you really don't have much use for it considering treasure chests and fights grant you materials in abundance and the merchant doesn't seem to have anything worth buying anyway.
The H-Content is all right. The biggest draw is that the artwork is nice (at least it strikes my fancy) and is completely uncensored so it makes for fantastic scenes. The biggest drawback is that there are only 12-ish scenes. And all of them are limited to battle-fuck scenarios. This isn't even a classic GOR game. Thankfully, there is no Game Over and you just end up back at base. The game does try to add scenes outside of battle but they're disappointing in more ways than one. They aren't backed up by decent narration and they reuse the same scenes from battle fuck scenarios. Which is a massive let-down. Plus, I'm never a fan of translucent characters in scenes.
All in all, the game is all right. Would I recommend it? Probably not Only play it if the character art strikes your fancy because the scenes, although too few in number, are well made.
