On 6/6/6 SEUM: Speedrunners From Hell will open the gates to hell for EVERYBODY!

On 6/6/6 (June 6, 2016) you will get the chance to speed through SEUM's devilish arenas yourself, as the fast-paced game will receive a public demo!

Run, jump, fly and teleport through 10 deadly arenas – each more devilish than the last. Play your best, and secure a top spot in the online leaderboards or find the hidden beer cans hidden throughout in every level. Hell yeah!
