There is a bug in the last version that was released. When you generate a new level, previously hatched monsters can carry over. This makes the game much more difficult on the second play through, even when you’ve selected the suggested easy (not so easy) mode.
I’ve fixed this bug, but the submissions are now locked. If you want to play at the suggested difficulty, I recommend pressing period (.) when you first load the game and select “Easy” mode. This gives you more time to react to monsters.
I apologize for the inconvenience.
I’ve included a guide section on the game’s page which includes some strategies that will help you beat the game on the first two difficulty levels.
