Good small game. I really liked the art style (the mascot is absolutely great) and the way the game was presented.
The little puzzle segments are nice and clock quite forgiving.
My main complaint is that it was too short. I think adding some variation in the puzzles and clock time would already be enough to solve it. Like, if you pieces you needed on the first puzzle were different each time, the path on the line one changed and the button/lever sequence on the last one too. Make it slightly harder as the levels go on (and maybe decrease the timer a little each time) and you could expand this into at least 4 to 6 levels easily, even without brand new puzzles.
All in all, great work! Really cool first jam game!
