"A charming swarm that crashes before it burns out"

About

Funguys Swarm is an action roguelike where you play as a cartoon mushroom fighting back against the Fireking's army. In a typical bullet-heaven style, you survive waves of enemies, automatically attacking with weapons you collect and upgrade. Each run involves selecting a character with unique abilities, choosing from a pool of randomised power-ups, and attempting to survive until the end of the stage. Between runs, you can spend resources on permanent upgrades for your forest sanctuary.

Verdict

There is a wonderful, chaotic bullet heaven game inside Funguys Swarm. Its charming mushroom heroes and satisfying wave-clearing action are easy to like. Unfortunately, that good game is trapped in a technical mess. Frequent, run-ending crashes undermine any sense of progress, while the screen becomes so cluttered with your own spell effects that you can't see the attacks that kill you. What's left is a recommendation with a heavy asterisk: a great time, if the game lets you have it.

You'll like it if …

  • +You enjoy the power fantasy and visual chaos of survivor-likes.
  • +A cute, vibrant art style is more appealing to you than grimdark themes.
  • +You're looking for a simple loop you can jump into for a quick session.

You'll dislike it if …

  • Losing a 20-minute run to a game crash is a dealbreaker.
  • You need combat where every enemy attack is clearly telegraphed.
  • The idea of a game becoming trivial after you've unlocked everything sounds boring.
