This is a really neat game, and one that should be showcased more to show what can be done with a simple game mechanic and GDevelop.
It has really good difficulty progression, the graphics, animation and sounds are cute and work together really well and I spent more time than I should playing it :D
This looks like a perfect game for mobile/touch devices. It's an one action game, which will make it appealing to casual gamers.
Other than some minor glitches (which are to be expected while it's a WiP), this looks like a great game, and plays really well.
Congrats on a great first GDevelop game (I can only assume you've made games with other engines/frameworks). I hope you plan on putting it in the app stores. Because it certainly looks, sounds and feels like it belongs there.
