Great game Sanchez Crew, love the keyboard+mouse control system and the game play is very addictive. I've noticed a couple of issues on my KS2 Next v2.09 playing the version included with the Steam distribution:
1. When you defeat the Boss, the screen scrolls to show the exit. However the character is off screen and I miss being able to collect the gold. Maybe just show an arrow pointing the way without the scroll.
2. When you die, the game does not return to the title screen. Instead it shows the game HUD on a black background and you have to reset the Next.
3. It would be great to be able to restart the game from the level you last played when restarting the game.
On the Steam Deck, I couldn't use the track pad or move the crosshairs at all. It would be great if you could support the twin sticks, it would play like Robotron then.
