Thank you for your comment!
Nice to hear that you liked our game and enjoyed the gameplay. We originally wanted to make a "Bonus Round" for the timeline with some fun modifiers, but we were running out of time quickly, so we had to scrap the idea and only keep the most important things. Also, we had a bug where the info panels for the bosses did not show up. There you could see that the collector’s effects were not permanent — sorry for the confusion :)
