Nice graphics!
I enjoyed the eyes following the mouse in the menu, small details like that make the game feels whole

Very nice to have the screen darken, multiplier with flames, HP hidden as your multiplier increase.
I usually go with +exp in this kind of game until I can then rank up upgrades, but that backfired hard as I was barely chipping the boss health. In any case, amazing skill tree and upgrades! Would’ve loved to see my current stats to help visualize the impacts of upgrades.
Great game, good job.
