this one was actually hard, it took three tries to get the right rng and strategy
(did it mostly without in/out room spamming, except with water bottle)
I may have found the infinite combo with baguette knife that kills every enemy after you kill an enemy.
edit: in actuality it just deals a lot of damage to all enemies, and continues dealing more if it kills at least one, but unfortunately the combo is not "infinite"
this game is very easy by the way, (I could easily play without picking up a single health potion) I think the problem is just with stacking the relic that heals you when you kill an enemy. it seems relatively common in the early game, and you don't have to have a lot of it before you reach the point where you only take damage if multiple enemies hit you at once (and there is always at least one enemy you can one hit).
edit: played several times, best game stats: 163 coins, 13 keys, 4 choppers, 5 snowmen, 6 amm_bush, 2 glasses, 3 angry bats, 2 big pockets, 2 bonkers, 3 magic feathers, 1 friendly soul, 3 baguette knife, 3 lemon, 1 dynamite boy, 1 pirate hook and 2 lance. (this is all from a single run)
it's surprisingly easy to reach a point where you just stay at max block and health without doing enough damage, especially against the healing enemy.
I like how shield is like a second health bar though. I don't think I've ever seen that interpretation of shield before.
if you do the math (dealer chooses randomly unless it's the last one) then in any case where neither of you have items and the shotgun has one live and up to four blanks, it is still better to take that 1/5 chance of shooting the dealer, because they are always equally likely to shoot either you or themselves, and you mostly only care about them giving a loaded gun back to you, ideally one that they might accidentally shoot themselves with after you attempt to shoot them again. (of course, with items it gets more complicated and sensible, but sometimes it's better to try and waste a bullet on yourself if you have bad items, just so the dealer doesn't hit you with double damage)
I also just want to mention that it's always better to shoot the other on the last round because skipped turns don't carry over after items, and the player always gets the first turn.
also, I don't know how I did it, but I made the r constantly teleport two spaces back and forth onto the arrow keys character (every time I used the other character). I don't know how I set this up, but I started the level by arranging the letters in a 2 by 3 rectangle.
but you can than predict the order of the cards, basically giving you free "hallway pass" if you put enough work into it. yes, if you change something, your score might change, but unless a card is burnt, or you have rigged the card order differently, you can just write down the order of cards, and maybe even predict when your opponent will bust.
