The perfect ‘waiting room’ diversion!

This classic arcade-type game is easy to learn. It gave me several lives from the start and allowed me to pick up where I left off in next game (progress wise) after I died so I didn’t have to clear the early stages repeatedly. Lots of fun!

Thanks! It was important to put gameplay above everything else. Let's be honest... no one wants to play a game where they die every five seconds (or they're forced to repeatedly watch ads). ;)

This is an awesome game. Changes every time you play. The patterns for the gloop keeps you focused on the task. Very cool retro graphics feel.

Thank you! The math that handles the drop rate and location was a lot of fun to work out.

Delightful Game

This is such a nice, simple departure from so many of today’s complex games. Couldn’t be easier to figure out. Couldn’t be more beautiful.
