I liked it! Upgrades and cart really sell the theme of dwarf character. His tween animations are also really cute!
Vampire Survivors clone is a pretty solid genre, always a treat to play. Yours had great feedback when smashing enemies with the cart
I think you maybe could have removed the HP to fit the theme a bit more? So to make it more about how efficient you are at collecting souls. Like, sure you can kill them with just your cart and reach 100k, you're just gonna take forever. You gotta pump these numbers.
Anyway, great job, loved it!
