9 levels! great - I think I came pretty close to the end. Gonna replay the game to get till the end. I love the idea of the new themes. Do tell me if you are looking for more assets, including more props and characters.
With regards to the navigation - I didnt realize that the game is controllable with mouse only. I believe the instructions were all for keyboard including some of the non-diegetic instructions that mentioned using ‘E’ to interact. With the default interaction inputs that exist now (Mouse + Keyboard) I would also add a keyboard for ‘continue’ text.
Gamepad would be really helpful - I think for an isometric game that would be extremely helpful, but I am that target audience that uses a PC with no gamepads.
