If you are stuck look at this guide:
I’ve 100% completed this game. Or altleast as much as you would need to. I’ve got pretty much every upgrade in the game and became an immortal god because of the vampire card. This is also based on the itch.io version as of May 2024, NOT the experimental version.
Here is my personal ranking of each card (I forgot the exact names):
Electric card: With high attack speed can shred through crowds of monsters early-mid game. Pairs well with cards that increase the amount of bullets like multi-shot or burst shot. Its quite literally free damage and i consider it to be the best early-game card.
Orbit card: Great for overall defense, which makes it great for early game and scales with bullet damage so a good add-on if you have a high speed build already. However it does have its glaring issues, mainly its low damage/the fact that when dealing with big slimes when they split, the smaller slimes can sneak into the circle. Because of this, it forces you to prepare counter measures like lava pool or ice. Great early game but even with upgrades becomes obsolete very soon in the face of red worms (Worst enemy in the game).
lava card: Completing for the best card in the game against vampire and electric, its great for both crowds and turtles. It also bypasses enemy armor and is viable mid-late game when upgraded. If i had to name any flaws with it, its the fact that you need to invest a large amount of upgrades into it, but besides that its one of the best cards in the game. It Pairs well with cards that allow more bullets like burst shot.
Armor shredder card: This one is a mixed bag. 10% of the time it gets rid of 10% of armor which sounds good until you realize you would need to hit 100 shots just to get rid of the armor, not even considering the health. It needs to be upgraded extensively which only makes it viable late game and at that point just get the assassin card which allows you to just bypass the armor itself with an extra bonus. This card just seems useless overall and is not something i would pick.
vampire card: This might be the best card in the game 0_0. Early game its good, mid game its amazing, and late game it makes you an immortal god, especially with high attack/bullet speed. Of course it pairs well with burst shot and multi-shot but honestly you could not spend a single upgrade on this card and it could still be extremely useful. If you are running a high bullet/attack speed build this is a must have.
Critical strike card: This is a also a mixed bag, but for a different reason. Its alrightish early-maybe-mid-game since you predictably need a lot of upgrades for it to be viable (btw 80% crit chance is insane) but under the right circumstances it can be an incredible damage dealer. But the reason im confused about it is because of the blue flame card which has the same effect and when fully upgraded actually prevents this card from working at all. Do not pair this with the blue flames and overall a decent add-on (And arguably better than the blue flames early game).
Multi-shot: Honestly haven’t used this card much but it seems pretty useless in the face of burst shot (like armor shredder). It might add-on some little extra damage early-mid game but by the time you have that maxed out late game you could’ve just used those upgrades on burst shot or blue flame.
Blue flame: As i mentioned it doesn’t work with critical strike but it still isn’t a bad card and might actually be better mid-late game. Yes the critical strike card does provide a higher damage boost but the blue flame allows for high consistent damage so this is a matter of preference.
Assassin card: Another great card. Allows you to pierce through armor (making armor shredder useless) and once the enemy’s health is low enough you can insta-kill. The armor piercing is already good enough but the insta-kill is the icing on the cake. This is basically a necessity mid-late game and you can think of it as a damage boosting card.
Ice card: I hate to say it, but this is another mixed bag. At first it seems like an amazing card; it slows enemies down (which also scales with max health), making it seem like the perfect card early-late game but it has one glaring issue. A glitch. Sometimes when effecting an enemy it somehow moves the same speed and ignores the slowing effect, which could easily end a run in the case of a turtle or red caterpillar. Still, it’s a great support card overall and i still wouldn’t ignore it, it’s just not a first pick.
Burst shot card: I know I’ve been hyping this one up, but for good reason. It allows you to fire multiple shots at once (to different enemy’s, unlike multi-shot) every 50 shots (bear with me there) and pairs insanely well with pretty much every effect card. Think about it, you can damage multiple enemy’s at once with 10 bullets of electricity or lava or even ice, which practically makes you unkillable mid-late game.
Honorable mention: Dice cards These are heavily underrated and are basically the key to getting past wave 30+. Their overhated because people dont like getting warm soup or armor on full health, but they ignore its obvious benefits like giving you more cards, allowing you to upgrade much faster. In early game it gives you a good foundation by giving you early accuracy and armor cards without having to waste rounds on them. Mid game it lets you upgrade your extra cards like lava or electricity much faster while also healing, and late game it can provide you with large buffs. Overall its one of the golden strategies to win, but in the end its up to you how you want to play, this is just some overwritten guide by someone with too much time on their hands. I’ll be surprised if anyone actually reads this lol.
TL:DR Vampire is op, Dice cards are op, orbit card is op, Burst shot is OP, become a minigun
