Koda and YandereDev are similar but there is one major difference between the two. YandereDev relied on his Patreons to actively continue wanting to donate to Yandere Sim whereas Koda relies on Patreons to set up monthly $2.00 donations and forget to cancel. If Koda finishes Tower of Trample he would no longer get those automatic payments and instead would have to rely of supporters to consciously start supporting his next project, which given his track record, nobody is going to want to do.
The only way I could see that happening would be if BoWei gave Koda the boot (Foot pun intended) and went solo or partnered with a reputable dev. Either way, regular updates would be an absolute must to repair the damage Koda has caused to Bo's reputation.
