I'm a bit late to the party, but would like to share my experience nonetheless!
First of all, the game looks amazing! It gave me a bit of a mix between Ratchet & Clank and Spyro games. The vibe, the way the combats works, the weapons, the enemies..
The game ran really smooth, I saw no glitches or bugs (besides the one mentioned below).
I also liked the save system. Having to look for a save made me think of older games, where you have to survive, adding up the difficulty etc.
The save brings me to what I disliked about the game. Often when I died, the items de-spawned. The most noticeable moment was with the waves during the Volcano chapter. In the middle building, there were some heals/ammo.. the moment I died and got back, these all disappeared.
This meant that I had to remember the pattern the enemies appeared, the way they moved etc. No ammo, no heals.. I had to do this quite often, which was frustrating, relying on luck that enemies dropped anything instead.
Talking about the Volcano chapter, the boss fight was quite ridiculous in my opinion. It felt more like a waiting game than a fight. Waiting for them to finish their different attacks to be able to do some damage in return.. It was really frustrating me. It didn't feel fair, just having to wait, always having to dodge etc.
That all being said, I enjoyed the game. I would return to it, if the things mentioned above were to be fixed, to make the game a bit more fair for the player. Now it is rather frustrating and repetitive at times.
Like others, I too made some videos on my experience. Feel free to take a look!
