/** \brief Hyperbolic platformer.
The implementation of the platformer from https : //twitter.com/ZenoRogue/status/1467233150380089345
To play , load platformer . lev ( e . g . ` - load platformer . lev ` )
Or create a new map by running with options :
` - noscr - canvas B - geo dbin - platformer `
Keys :
up / left / right - - move the guy
c - - clear the current room ( buggy , does not clear parts of the adjacent rooms )
g - - generate the current room ( buggy )
m - - see the map ( toggle )
p - - pause ( toggle )
z - - screenshot menu
2022-02-27 14:12:23 +00:00
v - - HyperRogue settings
2021-12-12 20:42:07 +00:00
q - - quit
s - - save to platformer . lev
1 - - place a small block under the mouse
2 - - place a big block under the mouse
3 - - delete the block under the mouse
Have fun !
