This was a really complex game, really good work with it. I particularly liked the voice acting at the beginning and the Greecian style of the whole thing. The powers and feel of the platforming were quite reminiscent of Castlevania - which is great cause that's an awesome series!
A couple of suggestions that I think may improve the experience though:
- I wasn't too keen on the colour palette if I'm honest - I appreciate the look you were going for, but it being mostly grey made the levels look a little dull (which was a shame because the modelling was excellent!). I think splashing hints of colour here and there would greatly improve it. Like maybe the torches giving off a vivid yellow light or the monsters having a brightly coloured mark on them, etc.
- I could hear the clicks of you turning your mic off / pressing the keyboard after some of the spoken audio tracks. You can easily fix this by using free software like Audacity to limit background noise and trim the ends of your audio tracks.
I saw that you wanted to expand this to a series so hopefully those suggestions are helpful in some way! :) Good luck!
