 - add argc/argv to gameInit? could be used to quickly start maps, verify
   replays etc.
+- maybe each map could have a target time embedded: when beaten, the map would
+  be marked as such
 - player name (modifyable via resource file)
 - popup messages? would be useful for several things: showing checkpoint times,
   showing changes in menu etc.
 - prevent time overflow! stop incrementing level frame once it's at maximum
+- make the racing module usable by itself, e.g. to allow making tools for
+  verifying replays etc., i.e. make the module measure time, count checkpoints
+  etc.
+- allow slowing down in air like in TM?
+- compile time option to choose how many maps to include (for platforms with
+  lower memory)
+- at the end check error handling, make sure the game handles garbage data in
+  resource file etc.
+- replay format
+
+=========== BUGS =================
+
+- drawing dithered transparent objects fills z-buffer in the transparent parts
+  and then the geometry behind it isn't drawn <- PARTIALLY FIXED NOW
+
+=========== HANDLED ==============
+
+- allow stopping car rotation in air like in Trackmania
+- car shadow? probably would have to be done as screen space effect with
+  z-buffer (shadow as 3D model would require collision detection and would make
+  renderer depend on physics engine). Maybe like this:
+  - project some point below the car to screen
+  - fill a dithered oval around this point, but only as long as the point's
+    Z coord is close to the value in Z-buffer
+  ^ PROBABLY NOT, tried it and looked weird
+- music?
+  - probably just make one long track, literally OGG or something, then make
+    that be played by the frontend just ALL the time (maybe with the option in
+    menu to just turn music off) -- simple frontends can just ignore music
+- sound engine: probably all SFX will be procedurally generated, ok?
+- make a simple rendering setting:
+  - will exclude images and only draw solid colors, let's say only 16, so that
+    memory usage is reduced, CPU rendering is relieved, executable is smaller
+    AND frontend doesn't have to use RGB565 (it can basically choose any mode).
+- drifting: passing some upper threshold on steering force should reduce
+  steering friction until reaching some some lower threshold again probably
+- Environments: just different textures for a cube inside which the tarck is,
+  the cube won't have the top side, texture can have transparency (sky see
+  through) <-- NO
+  - UPDATE: tho rasterization of the big cube could take whole screen: too slow.
+    Maybe just have a model + texture for each env? (still could allow transp).
+  - OR: environment could just be a sky texture (or just sky color?) plus a
+    floor texture? pretty KISS. SKY DOESN'T HAVE TO BE SPHERICALLY MAPPED, it
+    can simply rotate horizontally and shift vertically (camera will never
+    roll) -- not accurate but good enough. <-- YES
 - asset system:
   - assets are to be loaded from one BIG string consisting of substrings, each
     substring adds a map, replay, setting etc.
