Hello, that's a good idea but I have no more token left and I can't add such a feature on pico8. If I plan to port the game on a real platform, I surely bring that feature to the port :)
No no, the game is made with Pico8 virtual console. This system has a lot a restriction, 128x128 pixels, 4 audio channels, 16 colours... and 8192 "Tokens" to simulate program memory. One of the challenge when programming on this system is to make a maximum of feature fit in those 8192 tokens. When hitting the limit, the only way to add feature is to optimize the ones that already exists. At a moment optimization also hit a limit and you have the best that pico8 can offer :)
The other way to go further is to port the game on a real platform where there is no such limit, such as unity or anything else. But that is another story
