I like the core idea of this game and the initial set up is promising, but it's maybe a bit too ambitious for a game jam.
The idea of collecting memories to remember yourself seems cool, especially when you realise you need to find them in some dark desert kind of place. Collecting them is easy enough, but unfortunately there's no real challenge or narrative to go with it; I expected some kind of flashback or text or something to say "hey, this is who you are", as the premise seems like a potentially strong narrative.
The challenge should come from avoiding the spider monster, but unfortunately it's both too hard and too easy. I say both because if you're in the vicinity of the spider then it tracks you too quickly and it's difficult to escape from, but if you're not near it then you just never see it and it doesn't matter. There's also no real fear of being caught by it after a while; it caught up to me a couple of times but nothing happened, so I just didn't look around for it. It's kind of a shame because I really like the design of the spider and how it looks in the game - the glowing lights are a great idea!
Overall I think this was a good start, but it doesn't really seem to tie in to the narrative in a strong way. I feel like if the world were smaller and less empty it would help improve the sense of dread at the glowing spider, especially as initially the atmosphere feels quite unnerving. Well done for submitting!
