It would’ve been impressive enough to add a skill tree to a game jam entry—but somehow you managed to submit the game to TWO different game jams!
There is a lot of potential here, and once I figured out that I should match my attacks with the enemy colors (and avoid hitting them otherwise), the gameplay opened up to a highly dynamic experience. Skill trees may be intimidating to some players — so for a post-jam version I’d work on easing the player into this one. Great job!
