I've paused my 3rd playthrough of
Final Fantasy IV to play some short Game Gear games:
Started off w.
Sonic The Hedgehog Triple Trouble which I beat at 1st try, making this the easiest Sonic release I played so far

I also managed to beat my old highscore of about 80.000 pts in
Aerial Assault with now over 200.000 pts - almost beat the game but died off in the 3rd Mission soon as I was hit and lost all powerups.
Actually, though you're give a certain amount of lifes and continues, this game is actually sudden death all the time, bc as soon as you get hit once and lose all your powerups, the rest of your lifes get scratched off you in a blink.
And I managed to progress in
Ax Battler: A Legend of Golden Axe a little further than in my last attempt to finish it. Now I kinda break my teeth on Spooky Cave. This game got really hard really quick!

I wish you all the best of success at your current gaming projects!
