A fellow Lizard protagonist, hell yeah!
I had fun with the game, although I didn´t complete it. Perhaps when the save system is ready, I´ll give it another try.
I didn´t manage to get any keys, but reached the top of the pyramid. ("the way to the sky has been blocked" part)
My feedback:
-I feel the character takes too much time to reach its top speed when moving, making some jumps require additional momentum.
-Tendrils, Swinging ability. This one confused me quite a bit. I was expecting that at the end of the swing, you´ll have a speed boost depending on how fast you´re swinging, but after releasing from swinging, the character just comes to an abrupt stop? It still jumps a bit, however, which helped clear the courses, but I think this ability would feel better if it slingshots you far, depending on how fast the swinging is after releasing.
-Crouching submerges the character on the ground as well as sliding.
-I love the vibes the world gives! kind of a megastructure, ancient realm with bits of sci-fi and HUGE robots in between. I feel some textures didn´t quite fit the aesthetic (some cartoony cooblestone for example) but nothing too out of the theme.
-Character model and animations are great, I especially liked the kick.
-Getting Upgrades by removing your armor piece by piece is such a NEAT IDEA. Perhaps you could lose some of the benefits the armor gives you as well? (hazards are more dangerous, enemies hit harder, etc). I didn´t reach the end of the demo, so I dunno if there´s a surprise at the end which expands upon this idea.
