it's vampire survivors, except almost every weapon and upgrade is impractical and you probably won't survive no matter what you equip on any map besides the first one. (What i mean by this is only certain guns and certain upgrades will actually get you through the maps and it is highly unlikely the game will give you upgrades that are actually worth using. The grenade launcher is a great example of impractical, since most upgrades you use with it, will make you kill yourself. There is only one upgrade that removes the self inflicted damage and it pops up with two other upgrades as options. Obviously the self damage one is the only one that is worth using. The one choice working in this game happens a lot. Whereas in vampire survivors most upgrades and weapons will work and do the job. That is simply not the case in this game. If you do not use Yuki, Dasher, or Lilith your kinda just wasting your run if your on any map that isn't map 1. On top of this experimenting with weapons and upgrades seems really pointless, since once you find a character and a weapon that works, you minds well only use that. Since darkness 3-10 i've used the same character/weapon with pretty similar upgrades 11+ i went for random achievements. (Yes i have all the achievements so this review isn't simply a "skill issue.") Map wise Map 2 is the hardest, map 3 is annoying, while map 1 is basically the "i'm going to grind all the unlocks" map.)
Vampire survivors felt balanced no matter what you equipped. With some stuff being over powered.
While here nothing feels powerful enough, every starter weapon feels lacking, except for the dual smgs or cyclone sword. The grenade launcher would be great, except it kills you. Plus if you have the rune "Gun Glyph" you will get hurt by your own ability that activates every 5-10 seconds. None of the starter weapons feel fun to use, until you get upgrades and even then if the game doesn't give the right upgrades your basically screwed.
The bat gun is a great example of a useless weapon, that doesn't work on any map or with any character. To beat a map with this weapon on darkness 15 it basically just takes luck.
This game has 3 maps...
Vampire survivors has 20.
This game has 13 characters...
Vampire survivors has 85.
This game cannot compete with the competition in terms of content.
Gameplay wise at least in this you can control the direction of your attacks, and probably won't end up just staying still watching the game. (you'd play this game for every minute of the 20mins. Vampire survivors once you equip certain things, you can just put down the steam deck or let the computer stay open and the game will play itself.)
Conclusion
I can't recommend this game, when it's not even half worth the value of the game i can compare it with. You'd only enjoy this one more if you really like challenges or if you don't get bored playing the same 3 levels over and over, but even then there is less rewards and less content here then vampire survivors. I have 29 hours on this right now... I have beaten the 3 maps, unlocked all weapons/characters, fully upgraded every rune and even completed darkness 15 with every weapon/all characters. (There are 15 darkness levels - these are challenge modifiers to use on the 3 maps in the game.) Vampire survivors i have 65hrs, 51 characters unlocked, 143/228 bestiary, 156/225 in the collection, 174/242 unlocks, and 16/19 secrets. (I used to have everything unlocked, meaning they added a lot more content since the last time i played it.)
20 minutes till dawn doesn't seem to get new content?
Except what a new character every now and then?
Use this information as you will but i highly advise choosing a different bullet hell game.
