How you managed to get to 20k+ on the browser is beyond my comprehension...
Mine became unplayable by 3k .. lol, maybe cuz I didn't spawn enough turrets and it overloaded with enemies way earlier.. those powers actually have a timer that despawns, after 10 seconds, but at last minute change + adding new enemies and early level introduction, couldn't fine tune properly.. tested played it about 3 times and felt that the powers weren't dropping quite frequent enough..
ended up raising drop chance % and extending despawn period. Seemed to work fine for the first few levels, but not at "late game" haha
I'm definitely going to continue developing it until is good enough to have a proper "release".
Though the direction of were this is going, is still unclear.. just like when I started this jam, it ended up way different than I initially have thought and planned.
I'm extremely happy that you had fun playing it as I did making it.
Thank you very much for playing and taking the time to leave a feedback. Cheers!
