Standard Role Playing Game with a bit of Visual Novel thrown into the mix.
This is probably the most difficult negative review I've had to write so far, but there are just enough large (but not game-breaking flaws) to overlook.
(--) The level up/skill-point system is broken. Basically, they fall into 3 categories: combat skills, non-combat skills, and psionic (magic) skills. Most of the combat skills are divided into weapon skills, of which you should only put levels into one of them, which is based on your class selection. Every 20 points in a weapon skill, it raises damage with that weapon type by 1 per shot. This means that weapons that get 4 shots in one round get 4x more improvement than weapons with 1 shot - this is silly. The other combat skills: armor, accuracy, and evasion actually all do work alright, and are tempting to level even when they're not a class specific skill. Leveling individual psionics skills is absolutely broken, however. There is a singular root psionics skill which improves ALL the subskills in such a way that leveling individual skills is completely pointless. The non-combat skills are 'okay'. All they do is influence the RNG in various plot events that occur throughout the story, and a few give some mild combat perks.
(-) Psionics is not a very well balanced skill set. The one class that is dedicated to the use of it, it works pretty well, and a majority of the spells will see some use from it. Unfortunately, the 3 other classes in the game, while they're meant to have varying aptitudes with psionics, they're effectively bad enough with it that just attacking is the right answer.
(-) The inventory/equipment UI could be a lot better. It's a non-trivial matter (when it ought to be) of comparing the values of weapons.
(-) The characters are pretty shallow, although I'm mostly giving this one a pass due to the nature of the game.
(+/-) There isn't just attacking. There's 3 different attack types which have varying levels of shots fired per round, hit %, crit chance, and aggro drawn. The first 3 of those parameters are pretty boring - with some time spent with calculations, you can find out which attack type gives you the most damage for the weapon you're using. However, the level of aggro drawn is an interesting mechanic that I'll cover later.
(+/-) Lots of RNG. Can lead to some frustration, can also lead to some exciting down to the line fights.
(+) While it's nothing too special, I did like the flow of the plot and the setting. Based on other users' negative reviews, I guess your mileage may very significantly here.
(+) Games often have to sacrifice in order to provide a gamepath that isn't on tracks.
(++) Aggro management. Different actions will raise the probability that the enemy will target that particular character on their turn (and thus lower the probability of attacking the other 3 characters). This mechanic right here is significantly responsible for tactical decisions, and despite all the other flaws of the game, actually leaves combat kinda fun. It's an intricate balance between shaping as much aggro on your characters with the best resistances to the enemy attacks, but also still spreading enough damage to other characters, since even your characters with the best resistances can get overwhelmed by 2 consecutive rounds of the enemy focusing on him. Enemy will have enough mana to use an ability that will block a character from using normal attacks for a couple turns? Better ramp up the aggro on your Psionic.
In summary, I believe a broken leveling system (and its subsequent damage on the magic system) has wrecked an otherwise mediocre title that would earn a $10-15 pricetag.
