Really neat idea, and a fun one at that too! :) I love the fact that the whole dragon egg thematic all ties up very well with a little narrative that does not need to be overexplained, and is very tight with the overall gameplay too
The game overall feels kinda onesided when it comes to punishment. Its very light on the combat side, but game ending on the egg smash. I dont mind it being this punishing for the egg (its kinda the point and the gimmick of the game), but it feels disbalanced for the combat, as it kinda makes me not engage with the combat, because i get punished for breaking the egg, but the enemies are stupid and simple enough, that i can just run through them and worst case just “tank” one for the team. I think a tiny bit less health with heal spots could make the player engage with the combat more
I also think i could enjoy the combat more if the egg throw could be aimed with a mouse? It gets kinda input heavy to try to juggle all of it at once, and i think the juggling of the egg while fighitng is really fun, but it could be better if it wasnt discouraging because of the need to aim with the input keys during action / combat
Other than that, i think it ended up as a really cool game, and im glad i got to play it, thank you :)
