1.- Sometimes when you press "chapters" the game crashes, anyone else with this problem?
2.- Sometimes enemies get knocked to the other side of the wall or out of the building.

PS: I don't like how you or the enemy are invulnerable to each other if you are on top of each other.

(I don't think the game is very well made although its a great concept)

So far, all I've had was some Game Maker error messages when throwing a bouncing weapon like a brick or hammer, or when I try to use the shift-look just before or after a cutscene plays, but I can just click on 'Ignore' and continue playing.

I've encountered those error messages as well but sometimes it crashes when I hit ignore.

So far it's been mostly fine, but i have had levels unlock and give me scores for them despite having not played them.

I wanted to continue playing today, but I can't, it crashes 10hz.

Had a few graphical issues, gound textures disappearing. Mostly harmless.
I had a pretty bad one just a few minutes ago though; the game started flickering and crashed, floor textures were missing.

Also, fairly hilarious: on some levels dogs can walk through some walls. I had one leave the map repeatedly today.

Apart from that, what SCPM mentioned.

When I throw brick I get a error stating something about a steam achivement.

Guess there ain't gonna be any patches today...

Hopefully tomorrow. Can't wait to be able to play this.
