This Version of the Demo does not have the Save, load or help, the patch and upgrade or Achievement system implemented yet. I'll try and have these feature working within the next three or four versions top come. It also has a may-raid of bugs so please be patient as I'm the only one coding the game.
To install simply extract the Zip file in to a directory of your choice and run bubble.exe. Please note that you should play this game in DosBox with the following settings:
The Core set to DynamicThe CPUType set to 486_Slowand the Cycles set to 35000
I'm writing the game with these setting as default DosBox settings and the game runs really well with these. I have a P4 Duo core 1.7Ghz machine, and the game runs nice and smooth.
