Version 2 did not work for me (instead of the water loading in, there was a large gap where the title screen still showed and I couldn't seem to place bridges), but luckily I didn't run into any issues with the original. Overall, I really like the mechanics, though I think a little a bit more leniency when it comes to inaccuracy would be beneficial. Things like having the cursor snap to a valid area to place a bridge when near it would also make the gameplay a little smoother. Overall, I really liked this, and the environment is very well presented, and the ripple and water effects are a nice addition.
Hi Steven Miller, thanks for the comment! I've uploaded another version which fixes the bug you mentioned, thanks for reporting it. Placing bridge pieces is definitely too finicky; the snap-to idea sounds like a good solution. The worst part is placing the last piece and I wasn't able to find an easy solution for that (maybe a very large "final area" would work?).
