I love this lil game!
I really liked the music it was varied enough to keep enjoying it for quite a while, the art style and colour choice is really good-the lil spider is super cute. The idea of this game is also really great. I liked how I started to have a lil strategy with not just eating everything at one go but pacing it out in between making webs to make the best use of all that energy.
By the time I the tutorial was over, I already forgot that I was supposed to go look for the spiderlings -- too distracted by wanting to catch flies at first, until I saw a comment here saying they found all spiderlings. So I had to go back, restart, and this time with a goal:
So I do think the tutorial could have been paced out a little more, maybe let the player build the web two rounds or so before explaining that they needed to go look for the spiderlings, just to ensure that the player is not too distracted by all the new info about how to play the game by the time they are reading about the goal of the game.
Overall, love it, I'm really glad I stumbled on your game! It was exactly the kind of game I was looking for tonight.
