i managed to get the game to run by giving it the "Sprite/Bottle.png" the error was whining about.
Gameplay: even when it does function, the gameplay left me confused and underwhelmed. i think the main problem here is the lack of explanation for how to make different potions of different types. even an included README.txt with the potion recipes would have gone a long way to making me feel more motivated to keep playing. as for the vampire survivor part; it's conceptually interesting how you have to drag the ingredients back to the spawn point in order to collect them. i feel the main takeaway here is that the game needed to be more clear about what it is the player is ment to do
Graphics: the visuals are a bit basic, yet charming. aside from the missing sprite for the bottle, it's functional. i particularly like the main character with their cute little face.
Audio: only thing holding me back from giving it all 5 stars was the kind of unimpressive sound effects. the music was really nice. the shop theme has these nice and chill vibes.
Theme: having the fire heat a cauldron is a fine concept, but i was left a little underwhelmed by how much fire was featured. i feel like we should have a fire based attack, or have to collect fuel for the fire.
so a mixed bag overall. you did some things particularly well, namely the music. other things felt like they did not get the time or attention that they needed.
