The first thing I noticed was that while I originally expected the environment to have that “online textures” look, the textures fit together surprisingly well. You did a great job making sure your art was consistent with itself, and I think visually your game holds up very well for jam purposes.
I had some issues with input lag in WebGL(edit: I meant to say Wine) and particles flying over enemies at times, but beyond that I liked the number of small touches across the game. Having the cats fly to space covered in ash and soot was an unexpected extra detail I didn’t expect.
All in all, this is a very competent and well made entry that gets its point across well enough. By the end, I was concerned that the tank would start getting a second row of projectiles. The game doesn’t overstay its welcome and I think it’s a pretty impressive ten day package.
Nice work!
