The game is perfec. can you make online (i want just local). And i think you should add popular levels (level fun, level ! ...).
Sorry, I don't plan to add online mode in near future. I know it would be fun but it is really hard to work on (especially for me), and will probably require rewriting a lot of existing code as well. New levels are planned, but in next update I decided to focus on survival mechanics instead, as well more items, clothes, structures, etc. So I'm improving existing content and making current levels more fun for now. You'll see new levels in the update after the next one. (unless I split current update in two)
