Thanks for the comment!
I've made some adjustments to the combat for the post jam release, but it actually makes it more fluent and easier. I also increased the power of the powerups to slice through stuff faster. I think my intention for the combat was more to make it an enjoyful experience rather than tough.
I did also open up the path to the altar so its the first thing the player see when exiting the room. I have not added any better map though, and I'm not sure I want to. Have to think some more about that. I did make it so the minerals you pick up are collected and fills up a meter, which when full makes one crystal visible through the walls as a new feature. This will make sure the player does not have to play forever to find them and complete the game.
The game consists of four main areas which is not that much different, these are now made in to distinguishable biomes which I hope will make it more interesting to play. I'm not sure the game is more fun to play, but its funny how organic the game dev process is. Some changes you make into the project is easy to reject and remove, and some of them becomes like concrete and becomes like a foundation that defines it.
Thanks again for the nice comment!
