more of a shooter than a strategy game. And it is not that challenging. It worths a medium badge for completing the game. And it reminds me of the Bubble Tank series.
(SPOILER CONTENT IS CONTAINED IN THE FOLLOWING.) I think the parts that require entering of codes of "energy" "off" and "gravity" "off" are too harsh to be figured out.
Beating all leves and killing all enemies are not difficult, while the speedrun one is quite hard. The overall difficulty is quite balanced. The floor is a bit too slippery and the manuevering of the character is quite slow, making it hard to control.
An exabyte should be 1,000,000,000,000,000,000 bytes but not 1,000,000,000,000,000,000,000 bytes, so the answer should be "1" but not "3". Hydrochloric acid is HCl, while NaCl is sodium chloride.
The first few levels are quite easy, but the gameplay gets hard from level 13 or so. The overall difficulty is quite moderate. Moreover, it is quite challenging to manuever the ooze, although this might be a part of the gameplay.
The idea is innovative. But it is quite hard to manuever the sperm. Moreover the game is too easy to complete. More challenges should be added. One more thing to point out is this game should be categorized as sports and racing rather than puzzle. 3/5.
