The unused one is an upgrade that gives you a chance to burn enemies on hit, for some reason it didn't want to work and it burned enemies every hit instead of it being a chance, also it is literally identical to the poison enemies on hit upgrade so I just didn't use it.
oh ok, but that could been have great to have them stack. and how it didn't worked? since it is the same as poison, isn't it the same code, with just different graphics?
No, the code is different but the damage is similar to the poison so I saw no point in leaving it in. Also the bug is that it always burned enemies instead of having a chance to burn them.
I have like new 5 enemies already fully implemented in the game but I just have to add them to certain waves, unfortunately, you will have to wait a while until I start working on a new update, sorry, I am just really tired of working on this game.
