Hey, just wanted to let you know, I tested the game again and I fixed the issue with the tiles missing on level 1/2/3.
My PC gets laggy when playing browser games and I overlooked that, I just tested the tutorial and since downloadable version was fine and I was tired from the jam I didn't see that.
The theme was one direction so that's why Gunnie only looks forward.
I also set the default audio/music volume to 50.
And the coin ricochet won't target damaged enemies and won't miss most of the times. Altought the coin toss is still random, it's now easier to see the coin.
I'm sorry for the errors and I hope you can enjoy the game more now!
