Reducing time limit by player movement is actually quite interesting concept. It kind of forces the player to think what is the best route to "speedrun" a level. I enjoyed the platforming feeling quite a bit too!
I really liked the atmosphere & the visuals of the game! Actually I liked it so much, I hope there would be a follow-up/extended version some day :) Thanks for crafting such a nice jam entry.
Not sure what happened there. Just tested and did manage to level 6. Once I accidentally knocked a cat out of play field which led to soft lock...but that should not happen anymore with very high wall collision shapes surrounding the field.
