We apologise for the delayed feedback:
For a game that is usually not my style, this was really fun to play. I think you have a nice and unique interpretation for the Theme, which definitely sets you apart. The artwork and overall design for the game was fantastic, i did notice that some of the shooting animations aren't shooting in the correct direction, its worst when you are climbing above them. The use of music was good, but it wasnt anything that particularly stood out to me. It would be great if you could implement a more custom approach to the score with reactions to different actions taken in game. The idea that I thought could work is when you switch to a new host, changing the music. This will indicate that you have changed life form, and you could make it so the music gets faster as you lose biomass.
The GDD was short but contained some useful information. It would have been nice to see this a little more fleshed out, but that is one of the issue of a time constraint like the Game Jam.
Overall the game is a fantastic entry, please keep developing it. Great Job!
