Drawing a line is quite laggy and it disconnects too often. It would be much better if it automatically drew around the contour of the object instead of disconnecting. At least vibrate when I disconnect or something cause it's impossible to see what exactly I am drawing under my finger. The water is too rigid, it should be able to flow through thinner gaps and stationary water level should be horizontal not at a 20 to 30 deg angle. Would love to be able to shake the phone to get a few droplets of water to spill ^^ And, as I seem to write in most game reviews nowadays... way to many ads!

The game is fantastic but the amount of ads is COMPLETELY RIDICULOUS! The first lvls are really easy and you solve them within seconds only to watch two unskippable ads. So so so annoying. It's a shame, I would love this if that wasn't the case. I immediately looked for an ad free premium version and what can I say, it's like 20€ a month. Literally more than my gym membership.

the puzzles are fun, but there are ads after every level. I previously reviewed this game in 2018--gave it five stars and really enjoyed it for a few months, then moved on to something else. Tried it again today, and wow! the ad frequency is absolutely ridiculous and completely ruins the flow and pace of the game. very disappointed 😞
