To start with, the 1-bit art style of the game is a personal preference. I really like it! The mix of genres kept the game interesting . The story was well thought of, it went well with the game. The last level was quite tricky after seeing the right path, so I can't argue that the level design was quite good.

The use of a bone as a weapon was good choice since the character was a skeleton. I realized after a while that spam clicking could destroy the bone.

But besides that little issue, GREAT GAME OVERALL!

Just generally a lot of fun, I loved the sudden switch between art styles and genres! The art for both portions of the game were great by the way!

What a cool game! Even though your use of the "game over isn't the end" theme was sort of predictable, it was implemented so well that it didn't even matter! In that twist I completely had that "OMG no way!" reaction and was excited to see the new skeleton. Great job with the transition!

As for the platforming gameplay, it was stylistically consistent and fun to play. The music was great, the sound effects were responsive, thematic, and never got irritating to hear, the level design was effective and had the right amount of challenge (for an experienced platformer like myself, anyway). It got a little uncomfortable for my hands once I had to do multiple hovers and jumps simultaneously, mainly due to how I twisted my fingers around the keyboard, but over time I got used to it and I managed to beat the game. Also for the last spike level I was able to jump on top of the spike block and skip most of the level, so I'd recommend removing that gap unless you intended that shortcut to be there, because most players will go through that gap on their first playthrough.

The boss fight gameplay was super cool as well. It was a great contrast to the platforming, and it made a lot of stylistic sense due to the story writing. The artistic style was also a great contrast and it reignited my attention to what was happening on screen. The gameplay of throwing the bone to do damage was really clever, and it became a lot of fun as I got used to it, my one issue is that it's easily spam-able. It's clear that the devs are aware of this because they made the boss spawn in more goons then my casual bone-throws could take down (by the way, the boss fight's AI is fantastic, and all of the attacks were fair and balanced). I'd recommend making it so that you can't pick up the bones until they've stopped moving, that way you don't have to rely on that one playstyle to win. I also recommend that tweak because currently if you click fast enough, you can pick up the bone you just threw, making it disappear as soon as it appeared. These aren't huge issues, but just things to think about.

Also, having some sort of story transition back into the platformer would be nice. I more-or-less know what happened, but having it spelled out for me would be consistent with the game's theme and style, and it would explain what's going on.

Overall, great game play, fun story, fantastic 8-bit and adventure styles, and great use of the jam's theme. Nice job!
