Amazing game, great job.
I had a blast playing this game all the way to the end. You all put a lot of work and thought into the levels - and it shows.
Couple of things:
-Money was rather rare at the start and overly abundant before the end, maybe that could use a little balancing?
-Character felt very 'blocky' especially with close jumps that had a ledge overhead. It added to the difficulty, but became frustrating.
-Controls didn't feel natural, but that also added to the difficulty I guess.
-Curb some of the respawns, I just would enter and exit a room and kill everything over and over for drops.
I look forward to playing another game on this engine in the future!
