I love Vampire Survivors so this was a welcome clone for me, however didn't really see where the jam theme was used (growing in level?). Anyways, this could be fun if expanded!
Glad that you liked it :) I agree the theme is somewhat weak in this game but the "Growth" is from the spawning graves and growing number of enemies + you grow your character by upgrading it. I did plan some other things but per usual had to cut them to make the timeframe.
