If these guys are still going I think it might be time to white board this project.
From one Dev to another
1. Run through the bugs and make a list (may need several boards). Forget cosmetic graphics at this time the core programming need the most attention graphics is secondary to all else just look at minecraft and remember they did a lot with 8 and 16 bit graphics, no one builds a AAA game over night
2. Don’t be afraid to ask for help the community may have the help you need, some have already paid to support it. But paid or not the community may be willing to lend a hand to make this project succeed just look at Apache or firefox.
Don’t be a rob the builder (can we fix it … no its Fracked) and move on.
3. Project Management. Invest in a bug tracker most are open source (free) milestones help a lot and it shows the progress of development to the community and improves communication between dev and supporter. Forums Help but there not the be-all and end-all
(Optional) lower the price your rep is bad enough and the slow progress ain’t helping the cause
So at this time i would not recommend buying it but this might change in future (if an update is released before christmas)
A few thoughts (mainly to the devs but its general):
The motto I develop by is
“By small and simple things are great things brought to pass” (got that from a religious door knocker but it works)
The big picture looks good but building it, it’s like climbing Everest with your teeth you just freak out and start rocking in a corner saying this is not happening 50 times.
Just take small steps and by the time you realise it your half way there
So frequent small update are better then very long large update as it shows you still care about your project
