Noticed there were some unfair game elements so I tweaked it a bit 

-You can now jump higher in the void realm

-Portals to escape the void realm appear more frequently. Well, it's actually my fault. I forgot to delete something from the code and it makes people get stuck in the void realm for ages. So now, portals appear more consistently

-Lower health for enemies. You could now kill them in 2 hits instead of 3

-Enemy spawn rate is affected by the current score
