I can see and appreciate the effort, but the result is not good. What we have here is a short on content, incoherent mix of a runner, an on-rails shooter and an action roguelike, built on repurposed tech to a substandard quality.
You could see in the trailer everything nice about Whisker Squadron, so I'm going to be fully disagreeable here.
First, the obvious. This is not a survivors game, in any way, at all. Putting "Survivor" in a title was a ♥♥♥♥ move: they don't have the necessary vibes (I mean, it's a frantic shooter), and what they actually borrowed doesn't cohere with the rest at all: gem collecting conflicts with the main gameplay, and missable gems aren't exactly appealing. Meanwhile, it doesn't even seem to be a good marketing, given how crowded is the survivors market now.
The action part here is on the fence between a runner and a shooter, unable to pick a side, resulting in suffering. On a runner side, we have cluttered maps you're supposed to maneuver through, and a "tight boost" mechanic encouraging you to rush through narrow openings. On a shooter side, we have enemies shooting you at angles, and a combo mechanic encouraging you to kill enemies regularly. Nobody forbids enemies from disappearing from you for the combo cooldown duration - yes, combo has a cooldown. Nobody forbids enemies from shooting you from around the corner. Have fun.
Meanwhile, enemy variety is meh, weapons variety is also meh, and weapon limits - one primary weapon, one secondary that requires pickups for ammo refill - are kind of insane. Tying together moving and aiming (one stick/mouse to rule them all) is... a design choice, I guess. Boss phase changes and stage selection break the remains of the flow.
Graphic design here is hostile to the player: you often stop detecting enemies/projectiles in your own weapon fire VFX. Also, color coding - blue vs. lilac, really? - is weak enough to require full color sight to tell apart enemy fire from pickups (say, XP vs. lasers) even in normal situations. Also, it's hard to judge distances here (both for collisions, pickups and weapon effects)
On the roguelike part, you have all the standard trappings: XP/levels/upgrade choices, extremely watered down Slay The Spire-style map, all wrapped into the standard unlock-/numerical metaprogression. Upgrades are, for the most part, tied either to "tight boost" or combo; a half of them either outright useless or situational, most others are boring, hilarious cheese is non-existent. Map is also boring, the stage variety boils down to what powerup stages you pick, and how many "hard" battles you fight (hards are hit-or-miss, powerups tend to be either underwhelming or strictly necessary). Metaprogression is, again, boring: the unlocks don't change gameplay too much, numerical bonuses don't either - there is nothing transformative like +projectile count or +perk level. There is simply not much content here. The balance is off in extremely unfun way: for example, one type of powerup stage gives a random bonus of +50% to primary weapon damage, with one alternative being a bunch of metacurrency. Seriously?
Meanwhile, there are persistent and annoying bugs, such as parts of your build randomly disappearing or simply stopping working. Also, 100% grind is obnoxious.
