Hi, I'm the creator of LDtkToUnity. It's really awesome to see the package being used in this project! I discovered this through Github.
Once I was able to figure out how to play the game, it was pretty fun to try filling the rage meter. It was quite funny to imagine if there was a real player raging on the other end.
Though the game is a bit tilted against the "player" once the controls are understood.
When I would spawn enough enemies in, they were eating away at the player very quickly, as I was able to defeat him while he only covered ~33% of the map. Certainly satisfying, but definitely quick work.
Maybe there could have been some quick music added in the game? Even if it doesn't fit, It could potentially be better than silence.
I very much enjoy the idea and can imagine the amount of work needed to get this done within the jam's duration. Very nice, I enjoyed it :)
