Any controller support?

hi, I'm trying to get the 300 rounds survival achievement, but I have a hard time even getting to 20, enemies hit hard and not enough hp from their deaths. anyone got some advice oon how to get to round 300?

ive been looking for years. nows my chance to possibly have the dev tell me what that songs name is. ever since i played this game many many years ago, ive had that song stuck in my head. if its not a licensed song, could you upload the song to youtube? i remember spending at least a few minutes listening to the menu theme on start up all the time....

so, is 350 round in survival even real? and yea, what is the max round you got to? mine is only 60, sadly. well, yet only 60

I've been trying all time to get the stage 3 CG at first I thought I had to just close the game but, the bug remained, despite me breaking every single box and barrel I couldn't get the CG of that stage instead I got the one of stage 4 despite mer not completing stage 4 yet. Any help?...
