The concept is good and there is enough variation to add a bit of depth so I think the game was interesting. I've got a couple of feedback I wanted to give you which mean I find that really interesting :p
I liked the intro but it felt a bit weird that the buttons are under the spiders. It doesn't give the idea of a clickable item. Which in terms of UX is a bit strange. Could be interesting with some notion of collision between the spiders and the buttons. Or if you needed to make them go away to click if the gameplay was linked to that mechanic.
But enough with the buttons :D So the goal is to score the max to reach a glorious place into the leaderboard. So I would expect to have optimal controls to get to the max thanks to my skills until I do some stupid error.
I found the spikes a bit frustrating, well not the spikes directly but mostly due to the webs that really slow you down, so I wanted to go to the side then BOOM into the spikes. Annoying, I don't feel in control on what was happening. Too much web? To much velocity induced? No possibility to counter the direction? I don't know maybe a bit of everything.
Leaping spiders are a surprise and sometimes I can't even understand where the hell the went from?! :D Hate those! To fix that and to give a bit of challenge, some visual and/or audio cues could have been great. The idea is as a player you can quickly spot them (flat color shading effect, exclamation point), see the look in their many eyes and try to guess when they'll leap you at!
For the fall, I assume you used a procedural level generation. Which is great but some seeds felt really strange. I've got a empty corridor with one of my attemps. It was not skill but just luck that gave me a fairly good score.
Spiders are difficult to see due to the lack of contrast. So it's difficult to apprehen where to go. I died many times without seeing directly why.
Finally I'd have liked some skip animation or instant restart when I die. The animation is a bit too long IMO.
I mean that's a lot of feedback but as I said I liked the game. I hope it'll give you an interesting and constructive feedback on my humble sessions :) Well done! And godot is dope!
