Ay! A really cool game I must admit!
I enjoy how the game is designed and pretty it is!
I like there is no lives that we could lose after dying and would eventually make us retry to beat the level from the very beginning if we lost them.
Moreover the enemies have well animated attacks and are rather diversified. The shielded lizard acted goofy at some point, when I was too far away from him - he seemed to simply stand in one place and wait for me to come to him so he could attack me. I dunno whether it was your intention or not, but I am convinced he should at least take some steps towards the player instead of guarding one spot :P
I had little problems with the lizard boss, but that's a positive I guess! Bosses can't be too easy. I figured out after a while that you should jump over him and backstab him few times and repeat the sequence.
Some people have complained here about the sewer passage not being obvious enough and I think that can happen to be an obsticle for some folks - especially those who don't talk to the NPCs, so you could add some lighter texture on it to avoid such problems.
I am keeping my fingers crossed for the final product!
Last but not least, I got some questions:
1) When are you planning to release the final version of the game?
2) Where is the game going to be released? Only on itch.io or perhaps on Steam too?
3) What is the price of the game going to be? Maybe you're planning to publish it for free?
4) Will it be possible to beat the campaign in local coop?
