Extremely laggy when buying upgrade squares or moving ship parts, and ONLY then. It's odd, the rest of the game functions well. And this is the only window I have open etc, so it oughtn't be laggy.
About the inventory issue - there is not enough space. Enemies drop THREE different items each (shard/individual thing e.g. shell/egg) and you'll come across perhaps 3 different enemies. 9 total different drops, taking up a space each. Leaving 5 spaces for perhaps 3 equipment, shard and pet food. Not to mention other shards and potions or feather. You can't exactly avoid certain creatures on the way to a generator, and so having to leave behind a loot drop is annoying, especially since it is the quickest way to earn money.
This game does have its flaws, which I won't list because people have already mentioned. However, it'd be nice to know which way to go to get back to town. The first time I play I had to look on the internet to find out how to get back to town. Also, I don't know how powerful the special attacks are, and that would be nice to know.
Lost a life on 49 :( Oh well, try again... Also, I agree with the comment(s) about not being able to see the mouse clearly. I end up pausing to see where I am. And near the bottom left corner spawns the laser moving enemy (levels 37-38?). Be warned when going for the hard badge.
I like this game. Getting the badges gets easier once you get the hang of it, like love, you learn how to do it better, even though it won't always be perfect.
Nice game. I personally only use the default missile, nukes and drills (occasionally teleports...). The default missile is probably the best, to be honest, since by hitting slightly to the side you can blast the enemy into space/the sun/a shield, which kills them. 150 hp gone. xD
When people say certain powerups are bad, don't intentionally miss them. But don't risk your life for them.
Great game, simple and addicting. Finally got that hard badge, but I'll be coming back to play again.
