The game has potential, but has a serious lack of content and polish and is definitely not worth the asking price of £10.59 (at least not in its current state). If you badly want to play this game, I'd recommend waiting for it to go down in price or waiting for it to come out of early access.
If this game does look like your kind of thing, read this review before making your decision as the game is very flawed and just not really good. The following is my experience with Zero Gravity.
First of all, I couldn't get the game to run properly as the game kept defaulting to the highest settings. So if your rig isn't the best (or even your monitor as the game kept resetting the resolution) don't buy this game in its current state as it may not run properly. Thankfully, I got in contact with the dev and he gave me access to a developer's version of the game in which these issues are fixed. The developer was very helpful. However, I'm friends with the guy in real life so my experience with this might be bias. Also, not all of the issues were fixed.
I then went through the puzzle levels. They're very Portal-eque in the sense that everything takes place in a white testing space. I had no issues with these levels apart from the fact that these levels rely too much on dodging lazers. A feat that isn't easy in a first person game. There are also only 3 puzzle levels and they're all relatively short.
Next was the platformer levels. These are very unintuitive and very lazily designed. Every single level takes place in exactly the same environment with cubes in different places that act as platforms. The platformer levels just feel so lazily designed it's unbearable. Nothing in these levels are centred which is also very annoying. and very OCD testing. These levels just feel like they've been slapped together in a day or two. I ended up giving up on level 6 (of which there are 10) because the levels themselves are very unintuitive. All the platforms in these areas do different things but it isn't made clear what differentiates them. Yes, red ones explode but it's hard to tell what colour these things are from a distance. There are also spheres which act exactly the same as the cubes and, as far as I can tell, they serve no purpose but to maybe spice up the visuals and variety... which they don't.
Next was the EVA. This was probably the best mode out of all of them. Drifting through space and completing space walking missions feels so cool. I gave up on the first level though because I made it back to base but the game wouldn't actually acknowledge that I had. Very annoying.
I didn't even attempt to play the docking levels as I've played them before and they're too hard for any sane person to enjoy. I enjoy a challenge but that challenge has to be engaging and fun, which this isn't.
Overall, this game has massive potential but I urge anyone to not buy this game while it's in Alpha 0.1. It's just not worth the asking price of £10.59 at all. I may have received this game for free but if I hadn't I would've asked for a refund.
