I really liked the graphics! Are they procedural? Regardless they look great!
The concept of the game seems very fun! But atm it's pretty unbalanced haha. It'd be great if you gave more grace to the player to rest between fights instead of spawning enemies nonstop. Maybe even refresh cooldowns after combat.
It didn't seem like I could die so I was able to reach the end, haha. But one surefire strategy is to invest all in push upgrades and spam it on the last spider of a wave. It'll forever be pushed and no other spiders will spawn :^)
