I started the game yesterday and I look forward to getting into more challenging levels. I hope there are many more levels to come. Thanks for the fun! ### 2/5 — Too many ads *2020-08-01, version 1.05* Good puzzle game but the lengthy ad after every single level is beyond even other ad-heavy games. Really too much. ### 1/5 — ads *2020-07-14* ridiculous amount of ads keep this game from getting more than one star! ### 1/5 — Review type beat *2020-05-23, version 1.05* Too many ads ### 1/5 — Horrible *2020-05-21, version 1.05* Long pop up Adds.
