I really enjoyed this one, actually. I do miss frogs, but the theme is optional - so that’s okay. Gameplay for the most part is really tight, but can be unforgiving - what could be a cool upgrade is making it so when you pick up a key it auto-unlocks a door, so that you don’t have to go through each section more times than it takes you to pass the section. Overall, good job. I did manage to beat the game :)

I liked how the game incorporated the limitation - uncovering how the level evolves is fun. Gameplay was quite unforgiving, I could make past 3-4 levels and then gave up.

No frogs in sight sadly. The phrase "the level evolves when the door is hit" ... eeehh.

Also with platformers it is usually a good idea to introduce a "grace period" after walking off a platform, where you can still jump - otherwise it can feel extremely unforgiving, especially with a instant-velocity character controller.

The music was really repetetive, so I had to turn it off.

With a polished character controller and some different music I would totally play it though.

Does not use limitation nor frog themed.
