It would be great if you could customize your itch.io page a bit more to create a better user experience.
First of all, enabling the "Full screen button" in your itch.io settings would have been a big help, cus the window is very small right now. Additionally, adjusting the scale mode so the game can stretch to fill the screen would be beneficial. When I tried enlarging it in my browser, the game window remained the same tiny size. In Godot this is under Project Settings > Display > Window > Stretch (Mode)
I tried to download it so I could play fullscreen. For a game jam, removing the default payment option would be helpful so players don’t have to decline the $2 payment before they download it. Also, it seems like you uploaded your entire Godot project by accident. Next time, try to build and export it for Windows so it’s a .pck and .exe file that you can zip and upload instead. This will make it easier for players to download and play in full screen.
In terms of gameplay, it was overall okay but could use a bit more speed for climbing ladders and there were some animation glitches when you exit the ladder. Adding some background music could help too by filling in the silence when you are waiting for enemy patrols on the ladders.
Despite these issues, your game and art style definitely has a lot of charm!
