im have tested it and confirm it. Also you can do get past it by jumping on the water, but then the game might crash back to desktop after a few death (as im tested the area).
Howover im do not have the wierd VIEWPORT issue here throught as seen on your youtube. Im guess this has been happens because the original resolution game use does not present in fullscreen. so glbasic failed to set that resolution and still uses the desktop resolution? This is why im in my games allways uses the desktop resolution and scale to that. All you do need here to set a proper VIEWPORT and center it, then the issue is fixed. Im dont mind borders at all.0
This was a issue a user have pointed it back in 2019 throught.
Also the windowred mode does not work correctly as well and uses larger than the desktop, looks odd. Just resize it some where 64 pixels down or use the game native resoloution.
in Greedy Mouse im did that, while im in Power Up Elevation used its game native resolution (but scaling down if its dont fit as im remember):
GETDESKTOPSIZE x, y
FOR i=1 TO 3
LOCAL oldy=y
x=x-64
y=x*0.5625
LOCAL diff=ABS(oldy-y)
IF diff>128 THEN BREAK
NEXT
SETSCREEN x, y, 0;
Im do not remember where 0.5625 game from, property to retain a screen ratio format in windowered mode.
Im wonder why im diddent play the game, as im really like it and the flow and even nice camera scrolling as well? The atmosphere is excellent and well done! Love that.
