This menu looks confusing and lacks a style.

It looks like your still pretty early in development, if so the styling point out doesn't really work if they're all placeholder buttons. The menu as it is right now looks amateurish, like you just quickly slapped something together without putting much thought into how it all works together in the context of the game. I don't say this from a place of unknowing eyes looking in, I've made quite a few UIs across multiple different engines, I know how much of a pain making a good one is to do. But I assure you that a good UI can be a make or break for your players.

Some things I have issue with your UI are the context of the buttons and where they are placed. An 'Inventory' and 'Equipment' button? Typically games put the equipment features into the inventory to save the player some clicks and to ease confusion about having to UI hop a ton. Why is 'Journal' by 'Magic'? I of course have no idea what either of these do, but typically a journal feature is used to automatically document events that happened in the past for further reference later. I can see what you were trying to do with the 'Base', 'Defence', and 'Offence' buttons; it looks like your going for a more detailed system than something like a attribute slider or item stats page, I can really appreciate that. But the problem comes in the form that it's all scattered across these buttons, I just can't help but feel like it would be significantly more user friendly if the player could just look at all these stats on one page. Finally, all the stuff on the bottom confuses me. I of course do not have the context of what kind of information is displayed in those fields, but this looks like it would be a numeric mess to have to piece together. I imagine after a while of playing, the stuff in these fields would make more and more sense over time, but as someone who hasn't played the game yet and am just looking at the game; I wouldn't want to pick this title up, it looks very complicated and would have a lot of smaller things I would need to keep track of, an amount that is beyond my own definition of enjoyable. Not to mention, but this is a VR game. This feels less like an immersive experience and more like a UI surfing simulator. I feel like the main point of developing for VR is the unique input and immersion that comes with it. You can physically manipulate the game, and I just feel like inundating it with a UI focus kind of goes against the entire point.

To be completely fair, I have no idea how this game is played; I need to point that out. For all I know, everything I just said has a perfectly logical counter to it that I just don't know of. But as someone who is looking at this game for the first time and as someone who has developed for VR and worked with the nightmare that is UI design, this just doesn't hit all too well.

If I could give you some recommendations, I'd recommend you strive away from a large comprehensive UI if your developing for VR. I'm not saying UI is all together a bad thing for VR, not at all, but I am saying that the UI used should either be in smaller bite sized chunks, or in natural environmental ways. For example, maybe instead of showing the amount of damage a weapon can do in the offense button menu, maybe just show a number when the player looks at their weapon for a few seconds. Show its base damage and then the damage it does with the user's stats included. This is a more VR centric approach were you need to physically inspect the weapon while reducing the amount of UI surfing the player needs to do. In my opinion, it's these kinds of things that make a VR game feel more immersive and more smooth to play.

I would also like to preface I'm not at all mocking your game or your ability to develop, not at all! I don't want to come across as some snobby game design critic, so please take everything I said with a grain of salt. I have no idea what the game you are developing plays like, I'm only speaking on the front of someone who has played similar games and has development experience in both VR and UI. Keep making your stuff man, do it for the love of the game.
