About
Mycocosm represents the conflict that constantly rages beneath your feet - where resources are traded with unscrupulous dealers, battles are fought with endlessly reproducing enemies, and where chemical warfare is fought with terrifying frequency; all within a few grams of soil.
As a plant, your objective is simple: survive and grow. To do so, you'll need access to phosphorous and nitrogen, two difficult to find yet vital elements. Fortunately, wandering fungus spores will trade you these resources in exchange for access to your carbon. Everything comes at a price, however, and these fungi will take what they can and exploit you where possible.
Each spore offers a roulette wheel of possible trades - some generous, others stingy, and a few just plain unfair. Quick reflexes and wary dealings will be your only chance against the trading onslaught. Every exchange has a trade-off: how much carbon are you willing to sacrifice for these precious, precious nutrients?
Once you are well-established, it won't be long before enemies home in on your roots. Pathogenic bacteria will be drawn to your seedling, and they'll gather in great numbers to extract what they can. Your only hope resides in the antibiotics released by fungal allies. As always, nothing is free in the soil. Grow a strong root system to maximize your carbon supply, or grow leaves to increase your carbon income.
Whatever you do, don't hesitate. The microbial marketplace waits for no plant.
A hybrid arcade shooter and resource manager set entirely within the soil
Includes two game modes: Annual Mode and Arcade Mode
Annual Mode follows the genetic lineage of an annual plant through multiple seasons, where you must survive against changing enemies and environments while collecting resources to improve your future progeny
Arcade Mode requires you to achieve a high score while keeping your plant alive against increasingly powerful enemies and increasingly dubious fungal allies
6 plant types, each with a unique root system and benefits to enhance the soil ecosystem
4 allied spore types, including resource traders, weapon dealers, and host-boosting synergy spores
8 pathogenic enemies, including parasitic bacteria, berserker viruses, and monstrous nematodes
8 types of chemical-based defenses, requiring both skill and patience to inflict the most damage
Educational factoids to stimulate the mind between rounds, exploring the real science behind the ever-present fungi all around us

This is clearly some biologist's passion project. Feels a little rough around the edges, but very fun and surprisingly... realistic? If that's the right word...
EDIT: Everything I addressed was reworked, play this game. It's amazing. Original review below (before update) | v Before you read this, just know my criticisms are only here for the benefit of this game, not to tear the dev down or to deter anyone from playing. To start off, Annual Mode could definitely use some changes. I understand wanting to make it a kind of rouge-lite mode, but the differences in starting plasmid % was a poor choice. I basically just ended up swapping between the menus, re-rolling to get a higher chance. That being said, that's not the main issue I have with annual. That would be the plasmid % resetting completely every time you combo break (making the 10% plasmid achievement extremely frustrating). Possible fixes: 1) Remove the random starting plasmid % and have a consistent number of environmental debuffs, weapons, and enemies. OR 2) Have combo breaks set back the chance by a percentage of the amount gained from the combo. (ex. combo gives +1.2%, combo break takes 0.6%) I only have one major issue within the game overall, that being the leaves growth. I've found myself growing all the roots and only growing one leaf because any more growth drains Nitrogen and Phosphorous too fast. More time to get a better trade on the wheel doesn't matter if my other resources are draining so fast that I end up with a net loss, despite getting the best trade on that particular wheel. My only suggestions would be to have them drain less fast or guarantee that the best trades show up late game. Either way, I understand that it would be a lot harder to balance than mode-specific changes. with that all out of the way I LOVE THIS GAME AND THE HEART THAT WAS PUT INTO IT If you're looking for a good arcade game to sink a decent number of hours into, then this is absolutely for you. Challenge Arcade is definitely my favorite mode. There's a good chunk of customizability, and it's good for testing out how the different weapons and enemies function. It's worth every penny spent. Thank you to Alex May and Robin Ozard for not just making one, but two absolute banger games.
