The menu options are confusing, the first thing I did was quitting the game. A simple "Quit" text would have been easier to understand than an icon. I didnt understand much. I first lost 4 times. Watching helplessly while ants were beating the crap out of that poor mushroomish tree. After mashing most of the inputs on my keyboard I managed to have some lasers coming out, sometimes. It was very confusing. It would really need a way of showing inputs in the game and general better onboarding, it's very hard to understand.
Nice art. I like the playable mushroom.
