This game is quite fun! It's a creative spin on those block pushing puzzle games. The swiftness of the character, the tightness of the controls, and the time pressure all work together to make me really feel like a thief. Great work!
While playing, from the very start I had a bug that made the controls UI and some miscellaneous sprites cover a portion of the grid. I wasn't able to get super far because of that, but it doesn't look like anyone else encountered it, so I'll ignore it :'> (I'm on MacOS on Chrome.)
I solved the above issue by zooming the browser out a whole bunch. I suspect you'd be able to fix this by setting your stretch mode to canvas_items in your project settings!! <3
