Probably the first game I've ever seen that had Kamikaze crabs in it
The presentation as a whole was charming and very readable as well. I love how clear it is that sand blocks can only survive two waves. The animations for the crabs were pretty adorable ngl.
Really cool little concept here and damn nice execution of it as well. Love that you can only dig up wet sand. It's a cool little timer to ensure that you keep up the pace and dig up as much sand as you can.
That said, with how the difficulty was, I kinda had to only dig up 1 or 2 blocks for the first few levels and just use those, since it was usually enough. I think if there was something to protect then maybe it would have incentivised placing more blocks of sand around the level.
Or maybe placing blocks of sand at certain points in the level makes certain types of shells spawn or something to incentivise actually placing more blocks etc. I know the shells and starfish get thrown back into the ocean if the water reaches them, but new shells or starfish would spawn instead elsewhere anyway even if I didn't get to them.
Even when the blue crabs starting spawning it didn't really seem necessary to place too many blocks since I could just outrun and out-manouver them instead and use the block I had to shield myself from water.
Still though, the simplicity of the current system is definitely very easy to pick up and play with as soon as you read the tutorial, so maybe it's for the best. Also love the effects for the sand getting wet and dry
As a whole I'd say this a very damn solid game both presentation and gameplay wise. Kudos to you and your team for making this.
