The following review is based off my personal experience with playing this Game/Visual Novel... I try to be as brutally honest and detailed as I can, and these are my own opinions and thoughts, from one or more play throughs... The version this review is based on v0.1...
The visuals of this VN/Game thus far are alright... The characters look decent, and the backdrops are a mix of unique ones and others I've seen used in other VN/Games... The navigation system is a slight bit tedious, having to select a "NAV" button first before being able to switch rooms in the house... It would be easier if the navigation bar just stayed at the top of the screen while you were in the house, removing the extra step... Not sure the extra long penis is really necessary, it was the right size for the protagonists body frame, before it got altered... It always amazes my why these things always want to go for super natural sized penis' 9.5 times out of 10... The navigation map for going outside the house is rather basic, but works good for it's purpose... I would definitely suggest placing the text based navigations (that deal with the story) onto the map instead (such as when going to the library for the first time and so forth), because it sort of makes the map superfluous...
The script is decent, for what little there is so far... There are a few grammar and spelling errors, but it's not a lot... The premise of the plot, for now, revolves around a male protagonist who leaves home and decides to stay with a childhood female friend... He ends up being granted magical abilities, which he has to learn to use, with the help of another magic using female character... There are hints at possible intrigue later, but for now it's just foreshadowing... Currently, there really isn't much content, as it's just getting off the ground with it's development... The story progression, for now, is completely linear...
There is a Hint system on the protagonists PC that points out any story still needing to be experienced... But there are also a couple really quick things that can be experienced outside of the Hints... Not many, and they are very quick and have nothing really to do with the story progression...
The game day is broken up into time frames, but you have no option to skip time manually... Time flows during story content, but you have no direct control over skipping time... Which is something normally available in Navigation style game play with these VN/Games... Perhaps it just hasn't been implemented yet...
Also, it is not a Sandbox as tagged... Having a small set of rooms to go into in the home, and a couple of predetermined places to go on a city map, does not make it a Sandbox... Sandbox games allow for free roaming and the ability to alter the gaming environment... This is a progression based VN/Game, with a small amount of choice based navigation, not a Sandbox...
Overall, it is a bit of a cliché story premise of the protagonist having magical powers which are hinted at making his sex life better and/or more informative.. But it's still just too early to tell what exact direction this VN/Game will go... Will it be a porn fest, or have a deeper and meaningful story with rich characters and development? Only time will tell, but for now, it's just teasing some sex acts surrounding magical abilities, all within a slightly perverted young man... I can guess where it might be going, but probably better to wait and see... I'll most likely revisit this one again a bit later into development, to see if my slight reservations are warranted or completely off base... Until then, best of luck on it's development...
