I enjoyed this game. I really liked the cinematic the start and end. It's a bit stange that you can't die. Defeating the monsters wasn't really necesary; I just sort of barged through most of them. I do actually prefer games where I cannot die, but need to solve puzzles instead. But what's the point of the monsters and traps then? 

I liked how you used the same tiles scaled to different sizes, it gives the game a unique look and is something I wish I'd thought of :)

I too fell foul of the door bug which was a shame as there's some really good platforming action going on in this game. The movement of the character felt right and the hammer attack didn't feel too slow, so it felt like it just needed a bit of good timing. Platformers like this rely on good 'feel', and you nailed that. I wouldn't worry about posting a bugfix, even in the most strict jams, bug fixes are usually allowed, and this is far from a very strict jam! :)

Pretty cool, fellow "Constructor"! :)

My only issue is that I also got stuck in the last door on the level where there are 4 laser cannons (nice reuse of the bell sprite btw :).

I found myself mostly just swinging the hammer and letting enemies walk into it rather than aiming at them. I'm not sure where the chaining was supposed to occur. I didn't play all the way through though, cause I also got stuck in a door.

I don't think the movement is fitting for melee combat. It's very platformer-y movement, fitting the lasers and doors but not really the slow hammer. It's too quick and exaggerated I think. As such, I felt more like jumping over enemies than doing anything to them.

Fun! I'm in to the slow hammer swings. The character has nice, snappy movement. I also like the use of tiles, the game has a very distinct look. Unfortunately, I got stuck in a door and could not progress any farther:

That is very tight timing on escaping that room! I didnt quite make it and got stuck. Nice job!

Um..... what are the controls?
