Wow, how did you even think of this? I’ve never played anything like it, genuinely one of the most creative tower defense games I’ve seen.
I can understand others asking for numpad support, but I definitely feel like manually having to dial the numbers via the mouse adds a dimension to the game that would be lost with numpad support. I use a 12-button MMO mouse and as cool as it would be to speed-dial while hovering over the ‘call’ button, that would take away part of the experience I think.
Great work!
