As a platform puzzler this was solidly designed! The gradual shift from prey to predator was wonderful.
You might be interested to hear that our last jam had two constraints: it had to contain little to no text, and it had to use the narrative mechanic of anagnorisis, meaning self-revelation. I think had you submitted this to that jam, you may have won it.
What was especially good about this is that you trusted the player to piece the story together themselves. I enjoyed putting two and two together myself, and you even foreshadowed the ending (at least the one I got) so that the conclusion felt both surprising and inevitable.
Also this made me very nostalgic about all the Flash games I used to play on Newgrounds, so extra points there.
