My review summarized: "Could be great, but it isn't. Don't let this game waste your time."
This game has absolutely no idea what it wants to be, nor does it seem to have an effective path for arriving at whatever that end product is meant to be.
The UI is cluttered and unintuitive. You can only use items on your mon if you go to the Monsters section of the menu, select the mon you want, and then select Use Item. If your natural instinct is to go to your Bag to use an item, you can't.
The mechanics are painfully anti-player. While they seem to be attempting roguelike-esque difficulty, the developer has instead introduced tedium and confusion in place of engaging challenge. This is surprising, as there are many other Non-H games that have done a similar formula to this title without managing to make an experience that is irritating and wasteful of the player's time.
For example, you are actively discouraged from fighting mons, especially in the beginning.
You want to capture a new mon?
You need to be able to fully defeat the entire party in the random encounter. The problem is that most of these encounters feature 4 mons that you need to fight, two of which are the evolved versions of the two other basic mons in that encounter. This means you are very unlikely to achieve victory. Furthermore, you do NOT gain levels from winning battles. In fact, you gain nothing except the chance to recruit a mon.
What's the solution for this?
Spend 10+ minutes running around the barren map with an insultingly bad stamina sprint system, all while clicking on random objects hoping you find items that can be consumed by your mons to insignificantly improve their stats. Oh, but each mon can only consume three of those items in total, so no you can't power-farm them up.
I love difficult games. I love roguelikes, roguelites, and strategy games that really make me think. This game is not one of those experiences. I wholeheartedly do not understand the Dev's plan for this game, as the tagline for this monster-fighting, monster-breeding, monster-training game is, "Don't get bred by wild creatures."
That says plenty imo.
