Really fun game, it was quite tense trying to wrap my head around the pill colors and which buttons to press which made it exciting, got sucked into it quite a bit. Definitely has a lot of potentials. Well Done!!!

I'm feeling some inspiration from Inscryption here and loving it. I really like the potential of this game so I have a load of suggestions that you can do whatever the hell you want with.

In regards to an earlier comment on flattening the difficulty curve:

1.  A mode with just one pill per frog

2. A mode with only two frogs 

3. A timer bar as it's hard to gauge how long I have, and as the round automatically rolls on it feels easy to become left behind

My initial instict was to press W to place the pills, I'd say a control scheme as follows would be my ideal.

A /D - move left/right

W - place pill

S - skip currently queued pill

Some minor changes:

The controls menu is missing a key for Select Pill and Place Pill and automatically clearing pills after a failed round would be a shout.

Hopefully this helps, genuinely sick job on this!

Cool concept and presentation! I found it had an interesting learning curve but enjoyable!

Pretty interesting concept, its quite hard to play though never got into a rhythm, rip frogs.
