Two bits of feedback:
1. BUG: I set the timer to be really long, so it doesn't actually end during the round. The problem is, when you do this, the timer still counts down... I had a player randomly be set to their pre-mushroom health with the powerup ending sound, like, 10 minutes later. A fix to this or a cvar to make the buff last until the end of round would be good.
2. I want to be able to disable the sound effects for all players.

Its not working, gmod says its creating errors

The new update fixes many issues

The weapon base should be "weapon_tttbase" not "weapon_TTTbase". This would probably fix most errors

If you frequently get stuck, the server admin could adjust the model size of Super Mario by setting the scale to 1. This will prevent you from growing tall. Take a look at the last screenshot.

@Corvatile Yes it's certainly possible to add a convar option to disable the model override

Is it possible to disable the model override?

Sadly can confirm the last comments, whenever you touch something like a wall or a player you are unable to move. Even if you try to duckjump or the usual attempts. Anything I can try to make it work?

really bug addon

I get stuck every time i touch a wall :(

Please port various weapons so that they can be used for TTT2

I just uploaded the sandbox version: https://steamproxy.com/sharedfiles/filedetails/?id=2815367255

Yeah sure it's no big deal. I can create a sandbox version when I get home later.

Any plans on adding this to regular sandbox mode? It would be really cool to use this outside of TTT as well...who needs friends am I right fellas?
