It's good, but I feel like I want to be challenged a bit more by the enemies in ways that aren't just swarms. The moon laser level was the only one I died in, but that was more because I was trying to just focus on the big laser instead of dealing with anything else at all.
Generally feels pretty good, sounds could use some work though. The sprint behaviour is either a run (expected), run that stops immediately (not expected), and turning around 180 degrees (very unexpected and also disorienting). There aren't really any scenarios in the game that necessitate the quick turning at the moment because everything moves quite slowly, so maybe bring that onto a separate key? Also, landing doesn't feel like landing, it looks like I exploded but sounds like nothing happened.
I get that boosters lock you into the direction, but I'd appreciate being able to turn it off. As it stands, there's no real option to use it for anything other than travelling that exact distance, even if you just want to go up by a little bit.
It took me until the Moon level to realise that the 2 semicircles on the HUD were weapon statuses.
Actually liked the briefings and dialogue a lot more than I expected to. It's short and sweet.
