I forget to say that you can pause the game meanwhile alt tabing for right panel, sad I can't edit my message :/.

Hey :), a bit late compared to the guide creation but for the level from 2:25 to 2:46, you reaaally should had some info to help player with the satanic version / 3 stars (came from a bit more than 20 second late to nearly 40 sec in advance with tricks shown in the full walkthrough ^^') :
- For the right panel, you can alt + tab to write arrow direction (in a word or on a post it if you prefer).
- For the left panel, you actually don't need to kick out completely the coconuts from their "table" (don't know the english word ;p), you just need 5 hits and also the ammo can be overstocked more than how it look.
I had redo the level four times being 20 seconds short before looking for hints and it clearly save sanity :D.

I believe getting 3 stars on that final level is something a few players have struggled with. Once you defeat King Ferdinand for the first time in that level (achieving 1 star) you are given an item that unlocks a new area of the game, visiting this area will then help you achieve 3 stars and also unlock some end game content.

if you struggle to find where to go, a more direct explanation is here:
