Ok, this was a bit of a trip.
First and foremost, this is one of the difficult times I've had just trying to start a game. The amount of roadblocks it threw to try and stop me was ridiculous. I had the browser pop-up a message twice that it thought that the game was frozen and made me think it crashed and was unplayable: yes, I know you say it takes a long time to load in the description, but please, if there is some way you can help the load times or put a message in the game itself by the loading bar, it would help immensely. As a game developer, I understand the difficulty and you have my sympathies, but don't expect the general public to be sympathetic: they will just assume the game is busted and leave, and it would be completely justified. Even after the load times, however, I had no idea how to start the game on the main menu: I tried enter, space, the arrow keys, WASD, Z/X, ctrl, and all other common controls and nothing worked. Only later I realized that the game wanted Q to start the game: what other game in this world uses Q for confirmation!? If anything, E would've been slightly acceptable, but still, these are some crazy uncommon controls and again, it would be helpful if there was a prompt in the game to guide.
Ok, moving past that and starting up the game, the game is somewhat cool. Definitely gives me heavy Shin Megami vibes with its maze-like levels and use of the elemental press turn system (except it takes it a bit easier by only rewarding you for hitting weaknesses and not punishing you for hitting resists). I actually thought it was a horror game at first where someone is chasing you because of the warning meter, only later realizing it was a random encounter meter as seen in other games like Etrian Odyssey and such. Certainly an impressive game that seems to have a lot of potential.
Having said that, I easily found myself getting bored and dropping off. The maze was incredibly boring and repetitive with no notable landmarks and barely any fun interactions, and the map was useless because it was too zoomed in and I couldn't find any way to see the full map. Combat was just a rehash of Shin Megami combat as said before with nothing new to it, without any of the niceties that modern Persona combat has (such as previously hit weakness hints) and with barely any SP to allow you to engage in the elemental system without immediately running out. Definitely feels like there needs to be something cool and fresh in the game to serve as a hook, like a bit of story or characters or a more interesting world/maze to explore: I just felt lost and quit due to boredom and frustration quickly.
Again, it certainly does seem to have an impressive Shin Megami RPG-esque engine in place that could be used for great things: I'm hoping that this feedback, as rough as it is, can serve to help this game become something great and exciting in the future.
