With the mouse issue - it’s possible to use Q, E, and T to attack as well as your mouse buttons (as mentioned in the instructions), so feel free to have another go at it armed with this new information 🙃. tbf the mouse controls were an afterthought anyway, but I’ll bear that in mind for the future.
And, for someone finding themselves doing a ‘no attack buttons’ run, Wave 4 is a very respectable result!
Still, I’m very pleased to hear that you enjoyed your time playing this game, and please feel free to give it a rating as well :^)
