Thanks for the comment! I think I fixed that bug, I was able to do a full playthrough.
Awesome, I had another go and managed to do a full playthrough. Did you replace that level with the one (spoiler alert) with the slippery surfaces? That was pretty cool, kind of reminded me of Ice Climber (NES). The new love hearts are pretty cute too. Keep up the good work man, I'm a fan :) (https://twitter.com/MANvsPIXELS/status/1033302218965827584)
