Really well done! i love vampire survivors style games, and the one thing that can make them feel like a chore is when they're over balanced.
Cut to me 35 waves into hard mode generating $100k a wave and killing everything so fast i never even met the final boss, it didn't make it on screen. And this is an absolute win! you made it so fun to explore the various upgrade trees ifound myself planting new flower types just to see what their capstone upgrades were!
Only Real Critique is that the music gets a bit grating after 20 levels, but you added a volume knob so i can't even really complain, and until i full screened it the text boxes for end of level upgrades and capstone flower upgrades clipped out of the play area on the web version, making them impossible to read (can read them just fine maximized tho)
Incredible job! a contender for the top spots for sure!
