I broke down and bought a PSP over the weekend so I could play Lumines. And now, that is all I can think about. The game is brilliant, loads of fun, and the music is infectious. In fact, I have to post this game quick because the battery on the PSP is almost recharged. =)
Industrial Place Thingy is a game that is quite similar to Hapland. Both are games in which you click on little stick figures and devices to solve the puzzle and make things happen. There are four (4) levels to this one. The significant difference with games like this over other point-and-click Flash adventures is that it is possible to get yourself into a situation where you cannot win. Therefore, a "Reset" button is provided to reset the level and try again.
Although the graphic quality of this game looks a little rough, the design seems to have been well thought out and is overall quite challenging and fun to play. The game was created by James "Dangerskew" after playing Hapland "many times" and deciding to create one like it. So he did, and then posted it on deviantART and called it "Industrial Place Thingy."
UPDATE: Now also available from the same author, Industry 2.
Thanks to Kim for suggesting this game. And to jy for pointing me to the original author of the game.
