Finally got a chance to play this, I've been looking forward to it for a while.
Unfortunately, the game crashed about 15 minutes in and wasn't able to relaunch, but it was still enough time for me to have some thoughts about it.
The rail shooter gameplay overall is well done. Aiming felt consistent and easy (which is something I've struggled with in my own rail shooters, so congrats on getting it right here). Enemy variety is great, even if the enemies are mostly simple geometric shapes. The landscapes are awesome, I love how imposing some of the background features can look when they're just coming into view. There's only a handful of things that could be improved, there were times where it felt like I had to fight the controls a little to get the jet where I wanted it, and it was occasionally unclear where a track was taking me.
I'm less of a fan of the open areas, the aiming isn't nearly as consistent and some of the enemies are absolutely lethal. It's still impressive you got those done though, and even if they're not as good as the rail sections they add a lot to the game.
I liked the geometric visuals, they're a pretty good foundation. I think the game could use a bit more juice and better use of particles though. More sound variety would also be nice, but that's a fairly minor nitpick.
I would still be playing this now if the game hadn't crashed. Hopefully I just got unlucky and it's not a common issue. Great work on making this.
(still can't believe the coincidence of two rail shooters being made for a metroidvania focused jam)
