Nice, small and simple. This fluid stuff is kinda fun. I did have an intermittent issue with it not loading a level. It would say "Loading" and then "Level 1" (or some other number), and then never load. At one point my browser complained that a script was running slow. Maybe there's some weird infinite loop happening or something. It's not every time though, a refresh usually fixed it. The only other thing about the game, is it's hard to tell which tiles you will remove. Sometimes I click and get a whole square, sometimes it's just half. It's kind of neat to have some time-limited levels in this sort of thing.
Thanks for the review! :D Taking into account it's a jam game, I have in my mind there might be some bugs. For me, loading in browser sometimes behaves like in your case - I suppose it could be because of almost 300-1000 fluid particles in each level :D I'll investigate it further. I think I can add some indicator showing which tiles will be destroyed after clicking, thanks for a suggestion! ;) Further levels are indeed time limited - every droplet is drying in a moment and when all of them will be gone, the game will be over.
