This game shows a talent for level design and being creative with very little! The mechanic of re-using dead bodies is ingenious - though it may have been done before. Even so, it's still very neat!
The music is good too. The volume could have been turned down and maybe use AudioStreamPlayer instead of AudioStreamPlayer2D. On the title screen I was thinking that you had made a mono track.
This was very enjoyable to play through! Keep it up!
If you would be so kind and have time, I would love it if you played my game, rated it and let me know what you think in the comments! Thanks!
