Hey, I didn't rate because I'm not the intended audience for this kind of game. If you would like me to rate nonetheless, please let me know and I'd be happy to do so. Please keep my feedback with that perspective in mind too.
I found this game super tough. Like insanely tough. I'm not much of a gamer in the first place, but even so, it was sooo hard. I just died like 50 times just to get the grapple - and then I was basically stuck because I could not physically execute the moves needed. Pretty much called it a day and ended my run there.
But with that being said, this is the first time I've played this kind of platformer (seen some on youtube) and I did really enjoy it. So that means you guys designed your rooms and challenges well. In each room I was given what I consider the two most important things in game design - the ability to make different decisions and a clear upfront challenge. Also the archaeologist doing a Zelda when they got an upgrade was nice haha.
If I were to suggest improvements, it may not align with your vision of the game, but it would be to give the player a ton of affordances - slow the wall sliding down (I know its super slow already), reduce my hitbox so that I can get away with close shaves and not bang my head on jumps etc. But I understand if that's not the direction a game like this is meant to go.
Secondly - this is my personal opinion and I know nobody cares about this in game jams, but I'll put it out there nonetheless - I would really like to see the story implemented in the game itself. I personally consider storytelling a core component of what makes a game and basically a non-negotiable. So I don't align with the game jam values of "make a neat little game with unique mechanics and some polish." I like even the little games to be large and immersive.
I don't really need to go further than the first upgrade to get a sense of how much effort was put in and how well everything has been put together. I can visualise all the issues that I would've had if I had tried to develop this game. Great job to you guys.
Now that I've had a taste of this, I'll be playing other such platformers. I'd also like to give this another go when I have more time.
