I had bound death to spacebar for testing purposes, and apparently forgot to remove that. The small monsters spawn in random spots every 15 seconds. Not sure why you weren't able to find them. But thank you for playing!
Okay, I replayed it, now taking time to afk a bit before starting and letting some monsters spawn, and now it feels more complete. I love how at some point I become so huge I just start stomping these little guys ;~;
Overall, nice idea, I would've liked if there were some amount of monsters spawned around the player at the start of the game, so I wouldn't have to wait.
