Great work! I feel like the current levels could do with a redesign, and since the switch key pauses all of the moving platform properties, it should also pause the frog and tank properties, I personally died a few times from trying to switch with a tank but it shot me. Cool mix of platforming and puzzling, and could definitely add a lot of levels with new properties and enemies. You could even have secondary non movement properties (like color or camouflage) for puzzle purposes.
