Anyway, yes, definitely, you should use bombs, especially in the earlier games, where you get your bombs reset back to 3 as soon as you die. With that, only blithely not seeing the bullet that kills you excuses not bombing if you have one. Still, I generally reset if I can't get through the first three levels without using any bombs or dying.
The difference between SA and MOF and the earlier Windows games is that since it burns your power as you use it, you can't use more than a bomb every other spellcard on average, which means you can't just throw grace to the wind, and carpet-bomb the next to final and final bosses like you could in the first three windows games whenever you didn't like the spellcard.
I'll admit that bombs work significantly differently in SA and MOF, but I don't think it has the result you think it does. First I'll note that carpet-bombing through the Stage 5 boss is exactly
what I did in SA to great success.
The difference is that while you do lose power each time you bomb, you also get power back
for each spellcard you clear. In general, this is less than you spent, but sometime, particularly midstage spellcards, you get back more than enough for a bomb, which means that there's no reason whatsoever not to use a bomb. You just have to pay attention to which spellcards drop more power.
Also, this means that unlike the other games, you don't really have a good reason to avoid bombing in the early game. Saving up bombs is a paradigm that doesn't make any sense when you easily get bombs back. Bombs are not a resource that be saved up. Lives are the only resource that matter, although running out of power through excessive can certainly put ou at higher risk of death. If I reset every time I used a bomb, I'd probably have missed many opportunities to 1CC (1 continue clear) the game. Deaths... are another issue.
Which actually goes back to my original point. Learning how to dodge everything perfectly is, while nice in theory, not
the best way to beat the game. Most of my deaths come from a misguided "I can do this... I can do this..." mentality. Learning to panic and bomb when I was about to die (harder than it sounds) was very important to my growth as a player.
