WELL DONE! very nice production. I love all the music and the story was really captivating.. it was a little slow at first - but once you went to 'heaven' you had me.
My only critique would be to add more animation frames for Verm and other characters. Your art is so good, that it was marred by too little # of frames, making the walking animations not smooth and too fast/slow for their movements. (but maybe this was because of the itch.io limitations?)
My other minor critique would be to have the movement obstacles (or walls) more smooth. It didn't feel good moving Verm around corners, sometimes he would get stuck.. it didn't feel like good movement. Getting 'caught' on an edge is what I am talking about. Since it's not a platformer it should be really smooth movement.
Your creative use of parallax is just down right inspiring! great job there! Honestly it was one of my favorite parts going into a battle.
Also seems like a very ambitious project if you are to end up delivering a full game. The amount you will have to implement seems really intimidating! you probably need to put in up to 8-10 hours of gameplay?? or more?
