This looks amazing and sounds great. It's extremely well presented, from the menus at the start to the user interface and graphics in-game. Great job.
The movement is smooth, although it felt very sluggish. Then there's the tile size. It felt way too small for a classic dungeon crawler. It was very apparent when the prawns died and there wasn't enough room for them to die on the floor so they disappeared through the wall.
The transitions between the rooms via doors, or the TV teleporter, were very disorienting. You thought you could see through the door to the next room but when you went through the door you were somewhere completely different. Most of the scenery looked nice but was completely static and didn't really add anything to the gameplay. Why were we in a gym with lots of toilets? It felt a bit disconnected.
The inventory looked great and it was nice to be able to pickup in free look. When you picked items up the icons had no transparency to them which felt like an oversight, given how polished everything else was.
We picked up everything we found but didn't use anything except for the baton, the sledgehammer and the keys. We didn't get hit once throughout the entire game, even for the boss at the end. Were the red and blue bars health and something else, because they just seemed to be static for us. It was too easy to two-step around all the enemy. The small tiles made it very hard to know whether you were next to an enemy or a square away, especially with the end boss. Thankfully he was so slow that you just moved up to him until you couldn't move any further and then back away as he was turning.
There weren't any puzzles that we noticed and we didn't find any secret rooms. Did we miss some things?
Overall we were very impressed with the graphics and controls, but the gameplay and combat were lacking and in the end it wasn't as fun as it could have been given the foundations you put in. We didn't encounter any bugs that we noticed though, which is quite an achievement, much better than we did!
