Level 7 stage 3,the Laboratory is the WORST thing ever. Fix it immediately!
And I mean it because is unthinkable.
First of all the platform if despicable - besides the fact the platform in this game shouldn't be exist at all - and second the enemy are the most annoying thing because while you are fighting on a platform the others or they shoot you and they block you (while they damage your life) or the helmet jump you while you are busy fighting or dodge the attacks.
For fixing this abomination you just need to remove the platform, nothing more.
