Ay I like this game!
Shooting and eating enemies is a lot of fun, although I don't see much a point in expanding the web? It didn't seem to give me benefits other than just making the arena bigger.
The boss fight was too hard I'd say; even if you go in with full web you can't kill the boss, having to wait in place for some time, wich would be fine if it wasn't for the boss' insane attack; there's no animation for when it's about to attack, you just have to guess when the big spider will stop walking and immediately shot. It'd greatly benefit if it stopped in place a bit before attacking, had an animation, a sound cue, anything really, but as it is rn it's too hard to predict when you have to start moving.
Other than the boss, super great game! The gameplay is solid, the art is excelent and the music is really good. I really like this game!
