AHHHHHHHHHH
That was hectic! I got to level 6 before the lag was unplayable and I became dead (i played on browser)
The tradeoff mechanic where you go without a power for a round to get it back stronger, real risk vs reward stuff there, nicely implemented. The character models are really nicely done. The music is great. The jenga block system took me a few tries to understand - it encourages planning ahead in a unique way because you can't pick two adjacent upgrades. Does the height of the tower or the level influence anything or is it just a mark of progress?
I noticed the kill counter doesn't reset between runs, but I guess because of the unimplemented upgrade button on the 'you failed' screen that it's intentional and that you'd get stronger each time
Nice game!
