I logged in SPECIFICALLY to leave this comment. This seems like a fun game with potential, but I had two major issues. First being - having the controls be QWER and 1234 made it extremely difficult to select and cast, I often found myself wasting spells or selecting the wrong person.
But the real issue I had, was that out of nowhere, my spells would just stop casting. Plenty of mana, would try hot keys or clicking. And just none of them would cast anymore.
Way too easy, half way through the map it appears there's not even any more upgrades so it's just boring and repetitive maps with no interesting upgrades to drive progression. There is also a glitch/bug/exploit at the end of maps, you can click the check mark quickly and it keeps giving you the bonus money.
