This was so much fun! Roguelike shooter that looks great and plays wonderfully :)
I really like the look of this game and the way the visuals merge together. The style felt clean, consistent, and well-executed (I love vector art + bloom), and I really liked the individual sprites for the player and enemies. The particles looked fantastic too, detailed but not overwhelming, and really spruced the whole game up. I do think there could've been a bit more visual clarity differentiating enemy and player missiles from each other, though, I couldn't really tell in the moment what was or wasn't trying to hit me as I only had a split second to look before flying away. Perhaps making player missiles blue like player bullets could help?
I do agree that the balancing was a little off. Once I got a couple upgrades and could circle around groups or fly away while shooting, I didn't really have an incentive to do much else. It was a repeating pattern of wait until spawns, Time Sink through the crowds until I get clear space, then just drag them around behind me until everyone's gone. Don't get me wrong, though, the gameplay was still super fun, the feedback on shooting and hitting enemies was terrific- it just felt a bit limited in terms of successful playstyles, though I know that's the main balancing problem for any game like this, really.
The Time Sink meter in the corner could also be enhanced a little bit- I struggled to read the stats in the center, and although I loved the moving texture over the top it wasn't easy to tell how much power I had left. The ability itself felt very strong, which from what I can tell was the point, so no complaints there. It also felt really fun to use, sufficiently like a time-warp drive!
I know audio has been mentioned a couple times too, and I do agree there should be a bit more of it- I think even a whoosh sound when a bullet gets close to you or something, to help join what I'm seeing with what I'm hearing.
As far as shooters like this go, this one was really good. It felt super satisfying to play, and I'd love to play an expanded version after the jam :))))
