So as game do not have much content and it offers no replayability and almost no fun at all next update will be focused on some changes what will be possible to make with map generation, so as there will be faster game process ( no need to manually reset everything).
So as possible new game may be going quite stable and if it goes good, it will be good enough mini game, what uses same arrays.
I have some free time what I may use, to fully go into development :)
Plans for update 1.2
1) Options - Working bonus length time set, enemy, bonus min and max counts, Cave size.
Possibly, custom map size, but it will ask some mayor changes in code.
2) Automatic level progression (option what asks you, if you want to repeat the same game or go to next one.
3) Automatic enemy generation on game entry.
4) New generator algorithm ?
5) Some other types of bonuses, enemy sprites.
6) Somewhat better enemy AI
7) New game mode - Switch gravity and move physics objects to needed positions.
p.s These are just estimated changes, some of them have been started already (options), but others not. There may be some other changes too what are not mentioned, like other sprites .
Menu is more or less ok, you can possibly create huge maps now. Created option to round caves, for now really memory demanding.
