Thanks for the feedback! Quite a few people have been confused about "how to shoot" so I guess the not having any ammo at start should have been explained or hinted at a bit better. The movement is kinda intentionally clunky to encourage for more use of the gun to fly around. But I guess that design choice wasn't too clear either to some players at least. The spider boss is indeed very challenging and not intended to be fought at first encounter really. But it is beatable of course but a lot easier if you collect some upgrades first. The upgrades will for example tighten up the shot spread (and even magnetize the bullets more to the cursor instead of just going straight where the barrel is pointing) and give more mobility tools too.
