Edit: I reread this and I feel I came across as far more harsh and demoralising then I meant to be. If I can stress: I think the game is super cool, a great concept and clever take of the theme. You did really well. I was clearly just freshly frustrated by the bugs I encountered at the time of writing, haha.
Original comment:
I really like the concept and style of your game, but I had some issues that stopped me from really having a good time with it. I'm sure there were well-crafted interesting intended solutions for all of the puzzles, but the controls were a bit wonky and inconsitent, and the dead-body mechanic too chaotic and unpredictable that it was kind of just a case of mindlessly messing around until I made it past an area. It was also frustrating to make a difficult jump, only to realise you had to die to continue, without a checkpoint post-jump -- it felt like your achievement was for nothing, and made sections really laborious. Most critically, I had a bad bug with the checkpoints where they wouldn't properly update, and I kept getting sent to the one before the crusher wave section. I pressed on, and made it to the end of the platform ride, activated the checkpoint up the top, died, and then was sent all the way back down, so it was a little rough. Obviously it was a bug, not your intention, not your fault, but all the same I wish I could have beaten your game! I'm sure there was a lot of cool stuff I missed.
With all that being said, I adore the style and aesthetic of the game, the intro was super funny and it's conceptually/thematically really strong. Fantastic work, great job.
