i played this game on my school laptop i accodentaly found this while serchong penguin games and then i found it its called space wave :edit i beat all of the levels too
Skill issue Its easy on 2X speed lol (At least to lvl 5 i havent watch 6 yet :D) Edit: So i completed the game in like 10 min. Some levels were hard (i remember 30, 33 being prety hard) But most of the levels were prety easy
i tried it for myself being a 1 demon victor in gd i am, level 7 is hard (imo an insane 8 stars overall) but good wave practice (also i beat lvl 1 - 6 in 1 attempt so skill issue
