Good time Killer...
Ok. I thought this gam ewas quite good actually. To kill some time that is. Well made, sort of difficult, but kind of boring as well (b/c of the long trips to and from gas/sulfur) I just beat level 8 on your site (I think) and I plan to continue it later when I'm bored again. I wish there was a way to store Hydrogen and Sulfur IN your nest, and save it for later use, instead of having to use it whenever you collect it. To anyone who said they ran out of fireballs, you have to be smart and collect all the gas in each level to have enough. At the leve I'm at (8/9) I have 300 normal, 350 big, 100 laser, 50 fusion bombs, 100 paralyzers, and 25 big paralyzers. I got all the gas from each level to do that.
The graphics are nice, and some of the walls are a little off (I'm running into air) but overall pretty good. The link version thing worked fine for me, and it even saved my game from when I was playing on NG. I would put some sort of note on the NG version though, saying that it'd be easier to just play on your own site.
Overall, very good game, but not the ABSOLUTE best. Great job, and please continue to make these types of games. You are quite good at them.
