I really liked the idea of this game. Being able to choose between 4 different experiences is a really neat concept!
The stealth level was pretty challenging due to the number of skeletons there are as well as how fast they move. It seems they move on a set pattern so you can wait to see where they go. Leaving spawn can be tricky since 3 of them cross that starting zone pretty immediately. I would maybe remove 1 or 2 skeletons and make them slightly slower. I think some description of avoiding the skeletons eyesight and getting the key at the end would have been neat. The goal was pretty obvious but it would add more consistency with other levels descriptions.
The platforming level was fun, I liked that there were three different challenges for you to complete! The jumping is a little wonky though so you really have to take your time and make sure you are jumping then moving, but it all worked! I was a bit confused by the puzzle level, I liked that there were 2 different types of enemies and multiple rooms in the floor! I think some direction like other levels would benefit this one a lot.
I liked the maze level, it's neat that the juggler will keep track of how many balls you pick up, though I would have maybe preferred that be a part of the UI, that way you wouldn't have to leave the maze to check your progress. I think the skeletons were pretty balanced on this level, the camera and controls make things a little harder as you aren't the most responsive when turning and the walls can conflict with the camera angles. It was a good challenge to find all 5 of the balls and it took me quite a few tries to get them all.
I think the attack mechanic could be refined a bit more. Adding some visual flare would go a long way, but I really did like all the music in the game! That's something some other projects didnt have so it was cool to see here! Overall I think the game was fun with some nice variety in activities, and the skeletons were really nice!
