Glad you enjoyed it! There's no challenge you could leave it running and you'll eventually win haha.
Normally in RPGs, when you lose all your hp you die/fail/have to start again, here the Knight only gets knocked out and can still progress by getting back up and can also progress towards winning if the sword contacts a blob whist knocked out/in the failure state.
Yes but that is contextual. Some story driven games have challenge in making decisions and dealing with the consequences. Minecraft creative is a playground to build in. Your game is an action/fighting game - the mechanic, the skill to test, is in giving the player the right directions. If it contained some more silly/emergent gameplay it could be more of a sandbox type experience but it isn't, you have a clear goal of dropping all the monster's healthbars to 0.
