The shell shattering and the sounds are very satisfying! Very simple and nice gameplay loop with the shop upgrades and shaking the shell. If this game were extended beyond a demo I think the shell shaking mechanism would get a little frustrating, so maybe instead of shaking, you could hit the shell against a surface or something to shatter it in a certain number of hits that scales with how fast you hit the shell.

The shaking gameplay was super unique and fun! I wish there was a bit more content to hold me over. The content does get a little tiring like NicoSalad said so having a way to mitigate that would be nice. Finally the 2x was so op that I was able to get 10k in seconds.

I finished the demo and the game was pretty fun! I really liked the sound of shaking the shell it was super satisfying. Since the game is so short it doesn't overstay its welcome, but honestly I wouldn't want to shake my mouse around any longer than the length of the current demo, its a little tiring. Overall it was still a simple fun game. 

I did find one bug: the purchase option for ending the demo remained on screen after closing the shop menu

My main problem was how long it took to shake, but other than that pretty fun take on a clicker game

I think a "shaker game" is a fun spin on a "clicker game". I liked the hand drawn style, especially the titular shell sprite.

Cool game, I think visual queues about the durability of the shell would be helpful, also seeing your coins pile up somewhere would be pretty satisfying

I loved the sound effects in this one! They did exactly what they needed to and felt satisfying

It's a really short game, with simple graphics and mechanics. It's probably one of your first games, and that's a reason to say congrats!
