Seven circles seems pretty doable, got 92% so far, but Dash Hopes 3? Man, that song is psycho. The note line moves way too fast so you need to be really precise with hits else you miss and die instantly...
Well, now I finally completed the game, and then my internet died for only a little moment and I didn't get the badge. I feel like I want to kill something :<
Lasers: shoot at your current position. Green bombs: aimed at the position you're are going to be at in X seconds assuming your current velocity. While the yellow area balls and lasers are just pure avoidance, you can easily avoid lasers by slowly moving in one direction until you hit a wall, than try find a gap and go the other way. For green bombs, try juke(=fake) the direction you're going.
For the first 5 stages, I took that tri shot machine gun, and combine it with 3 barriers, and 1 barrage tower. The barrage tower is imho even better than sniper, even against armoured targets, even though it doesn't have armour penetration. For the last stage, I pretty much did what Kenji suggested above, except I switched one damage boost for a barrage tower.
It's funny how after I completed this game and I go back to RL, I still think I'm Sarah and trying to do gravity switches. You really messed my head up haha. But I love the game, very cool gameplay 5/5
Cool graphics! Coding up a software rasterizer and raytracer atm to learn about graphics myself :D Perspective correct vertex attribute interpolation is a pain in the *ss
This game is nice and fun, however, it's a little annoying that you need some luck to get the ultimate achievements for a level. I'm not saying that it's all luck, but still, it's too big of a factor for a skill game. Still gave you 5/5 though :)
Bug: when you shoot a grey cell, on some rare occasions, even when the goo should have faded already, the graphics stay there (in screen space) until you die or win. Quite annoying...
