It's very creative. However, searching for enemies is like searching for a needle in a haystack, so I would suggest a minimap option. Furthermore, flamethrower seems to work only rarely, although I'm sure I followed the instructions correctly. If you add a story, and maybe more skills, then this would be a very good game. For now, 3/5.
It's an ok game, fun at first, but gets repetitive and boring later. The jumping and running seem rather jerky and I don't like how a stream of monsters keep spawning in your face, which causes you to take unnecessary damage. Overall, it's a decent game, though not very polished. 3/5.
Foolproof method to get hard badge: Avoid all bubbles and powerups except minesweeper and invincible. Destroy the mines by ramming into them if you have invincible, or shooting them if you have minesweeper. By avoiding bubbles, you prevent your size from increasing so you can just evade and wait for good powerups. At the same time, destroying mines gives you good points and does not increase your size.
Quite fun, but the gameplay is somewhat linear. The only challenge in this game is getting yourself to the next key, and the next and so on. The rest is self explanatory. Overall I think it deserves a 3/5.
A suggestion: How about letting pets pickup loot on the ground? That would save players so much time because the terrain makes it troublesome to collect loot.
Great game, but improvements can be made. For instance, others have mentioned that a mage character cannot get far because of the weight limit. Apart from that, the music seems rather repetitive. Anyway, I'm glad that changing your system time will still cause eggs to hatch. All in all, 4/5.
Without persistent upgrades, there isn't any incentive for replaying older levels. Each time you start a level it seems as though you just started a new game, and have to earn all the upgrades yet again. It's a good game, but can be improved on. 4/5.
