its a good game but its insanely annoying on stage 4 after 1st boss.
there is no getting by that. your best hope is to dodge enough bullets just in time for the first grenade to go off (you can kill all 6 with 2 grenades)
when you start out your immediately in range of the 2 on the far left and the one on far right (from their formation)
taking 2 steps back pulls the one in far right out of range. but the 2 in far left are still in range to fire even though your on the other side of the screen (directly opposite of them)
I believe this is a programming error and the 2 far left were ment to fall out of range as you move down to the right (allowing you to move back even if its with a slightly better chance)
but to put it bluntly stage 4 after boss is nerfed. you can't beat that one, don't even try, it would be argueable if you changed levels taking your HP from the last with you, but you start with 100%hp and 100%armor.
if you could take maybe 6 shots instead of 3 (common you got armor on for crying out loud) then it would be beatable. almost easily beaten. because its necesarry to take 3 or 4 shots of fire to strafe into safety for the grenades to go off.
and yes I did just rant about that for this hole review because its a huge issue in your game that needs to be repaired or lightened.
1- patience isn't going to work on that level you start the level being shot at.
2- hide and seek??? there's nothing to hide behind at all.
3- ok grenades was actually a good tip because 2 will kill all 6 (you damage the scientist just a tad.
thank you for your time, if this problem is fixed I'll PM a revised review to you
